ChatGPT – What to make of it

It can write essays, explain more or less anything you might ask, it can even pass many written exams on all kinds of topics

If you’ve been paying attention to the technology scene recently, you cannot fail to have heard of ChatGPT. What is it? Quite simply it’s a chatbot, a type and read interface for version 3.5 of the GPT engine developed by Open AI.

If all that sounds confusing, a chatbot is artificial intelligence (AI) software, in this case presented as a webpage, where you can have a conversation with a computer program. You type in a question and the chatbot sends a reply. Repeated questions and replies form a conversation, in ChatGPT’s case a remarkably smooth, almost ‘human’ experience.

If you haven’t yet tried it, then you really should. It’s free and very easy to use. I encourage you to visit chat.openai.com, sign up for a free account, and type a question. There are no rules about what you can and cannot type; ChatGPT is accomplished at understanding ordinary language and gives good, conversational replies.

Assuming you tried it out and have found your way back to my blog post, I’d like to explain a bit more about it. ChatGPT was released as a website at the end of November in 2022 and has grown in popularity very, very fast. If you tried it out for yourself, I’m sure you will understand why. It’s compelling, it can write essays, explain more or less anything you might ask, it can even pass many written exams on all kinds of topics. And version 4.0 of the engine is already available as a paid option and is far more capable. It can take images as input as well as text and has, for example, built a working website based on a sketch and a description of what the website should do. That is little short of astounding!

The company, Open AI, was created to work on artificial intelligence with safety very much in mind. Sometimes, ChatGPT generates false answers; that can be an issue but it is not deliberate. What if more advanced AI became able to reason as people do, what if it started to think and develop it’s own goals, and what if its intellect became faster and more nimble than our own? Could we prevent it from taking over? Would it be benign, or might it become hostile? Would we be able to control it? These are serious issues. We need to think these things through now, before it becomes too late.

I don’t want to be alarmist, and AI as we currently experience it is far from becoming a threat. It may prove useful in many ways and we’ll see that begin to happen very soon. But we’ll need to manage it in ways that prevent it helping people do bad things. We don’t want such technology to enhance criminal activity, for example. So there’s a great deal to consider right now, and the need for that will only increase as AI systems become more and more capable. For more on this I recommend Sean Carroll’s podcast episode 230, linked below.

I’m going to close this blog post at this point, but I’ll be back soon with a sort of interview with ChatGPT. I’ll ask some questions, let the software answer, and publish the conversation.

Meanwhile, have some ChatGPT conversations for yourself and see what you think.

Notes from bygone years – March after March after March

Two years ago

There were no posts in March 2021, but I walked a long section of the old Thames and Severn Canal. The photo shows the towpath on the left and the bed of the canal on the right. The canal is being restored, but it will be a long time before this section can carry barges again.

Five years ago

In March 2018 I posted about moving into our new house and adding an extension (‘Our new home in the Cotswolds‘). The building work was disruptive in the extreme, of course. We had to move out for four weeks, and make do with just part of the original space for much longer than that. But it was worth it.

The lounge in chaos — We used to watch TV here!

Ten years ago

In March 2013 I wrote about a TED interview with Elon Musk. Perhaps you haven’t heard of the TED talks, but everybody has heard of Elon. The post is interesting: Musk was already experimentally landing rockets ten years ago, and TED continues to be a great ideas platform. Take a look and explore the links in the original post.

Fifteen years ago

I reported on a meeting at home in March 2008.

Rachael also shared a picture of an old-fashioned plough making furrows. The soil needs to be churned up and overturned before something new can be grown. There is a necessary process of breaking before the land can be used.

We thought about how Father releases us from ourselves. At the beginning he said, ‘Let there be light’; he still speaks those words into his people today and pours light into the darkest places in our hearts.

Twenty years ago

March 2003, another early blog post about a meeting at home. This time there were only two of us, but we heard such a lot! For example, that the tiny stonecrop, the great cedar, and the mighty oak tree were all planted by Father’s hand. The important thing is not to be big or strong, but to be planted by the master.

Twenty-five years ago

And in March 1998, Donna and I were married!

SpaceX’s Starship launch

For this first flight both parts of the vehicle will be lost after landing on the sea (but hopefully not before)

Elon Musk’s company, SpaceX, is close to the first launch of their new spacecraft – Starship. This is an exciting step forward in space flight technology as fully reusable Starship versions are planned to return NASA astronauts to the moon, act as orbital fuel tankers, take people and materials to destinations throughout the solar system, and colonise Mars.

The world’s most powerful rocket is likely to make its first orbital flight attempt during March. Whatever happens, the attempt will be spectacular in the extreme! With twice the thrust of NASA’s SLS rocket, SpaceX’s Super Heavy booster will attempt a launch from Starbase on the Texas coast, heading east. The Starship will separate and pass between Florida and Cuba.

The Super Heavy booster will attempt a landing on the surface of the sea, offshore of its launch point. When fully operational, SpaceX intends that Super Heavy boosters will return to the launch site to be caught in mid-air by arms on the launch tower. Starship will attempt a landing, also on the sea surface, north of Hawaii, but again, the intention is to eventually catch Starship at the launch site as well.

For this first flight both parts of the vehicle will be lost after landing on the sea (but hopefully not before). It’s likely they will attempt to hover above the sea surface to practice the manoeuvre they will need to perform for a catch. Once landing precision is good enough, SpaceX will attempt the first catches. But that’s something for future flights and will depend on data returned from this first attempt. You can’t put a note in your diary to watch the launch as we don’t yet know exactly when it will happen. But I’ll keep you posted here on JHM.

The previous step forward for Starship was a static fire by the Super Heavy booster on 9th February. This is worth watching in this video clip from NASA. Thirty-one of the booster’s thirty-three engines fired for the duration of the test, one was not ignited at all, and one shut down early. The engines fired at half thrust during the test, but for the first launch they’ll be run at 90% thrust.

Making a fresh start

I sum these topics up on my Twitter profile as biology, web, science, technology, family, faith, history, and travel.

Having recently restarted blogging after a long pause, I’ve been thinking through how best to move forward – what should I change, what should I drop, and what should I keep?

Today’s post explains some of this, I’ll share what I’m doing and what I plan to do next. I’ll consider any comments you may leave, either here on the blog, or on Twitter or Facebook. But here’s how I see things right now.

Buy me a coffee

I’m offering everything I publish for free, but will always be delighted to receive a small gift, especially if you have sold or republished something (though even then it’s optional). Details are at coffee.scilla.org.uk .

Cruising the Gospel

This is a moribund blog that I’m in the process of restarting. I’m not sure yet whether to continue it in its present form, or to roll it into Journeys of Heart and Mind (JHM) as a topic in its own right. Currently I’m inclined to keep it as it is, and perhaps generate some PDFs from each book I complete. See it at gospel.scilla.org.uk .

Gateway

My Gateway site is mainly for my own use, but it’s full of links about Cirencester (my home town in England), local time and weather, some Christian links, local and national news, science and technology links and so forth. Some of you might like to take a peek. If so, head to gate.scilla.org.uk .

JDMC

JDMC stands for Jesus, Disciple, Mission, Church and is an introduction to Alan Hirsch’s Forgotten Ways. To learn more and download a copy to print (or read online), visit jdmc.scilla.org.uk . I need to update this booklet and plan to when I have time, unfortunately the web links in the PDF open OK, but using the browser to return take you back to the title page; I’ve been unable to fix this so far. If you open the links in a new tab you’ll be OK, but it’s easy to forget.

Journeys of Heart and mind

I intend to continue with this more or less as it stands. That means a mix of topics will appear here, articles about all of the things that motivate me as they occur to me (so in no particular order). I sum these topics up on my Twitter profile as biology, web, science, technology, family, faith, history, and travel. Others include photography, astronomy, spaceflight, archaeology and a few more. One thing I will add is a way of seeing just posts on one of these topics at a time, I think that will be useful; not everyone wants to see everything. You’re reading on this site at the moment.

Photos

I use Smugmug to display my photos and will continue with this, but I need to rearrange things in topic folders to make it more usable. Visit photos.scilla.org.uk to browse my all time favourites.

Twitter

My main Twitter account is ChrisJJ, but I have a second account, JHM. I haven’t used the JHM account for a long while, but might post tweets about faith topics there, and everything else on ChrisJJ. My mind is far from made up on this as there are quite a few pros and cons.

Climate change – What can I do?

By showering less often I’m cutting my water use to less than half, and turning down the flow rate reduces water use by about half again.

I’ve just watched the latest ‘Just have a think’ video from Dave Borlace. I really enjoy his videos – they are well produced, clear, uncompromising, polite, thorough … well, you get the idea. The latest one asks what we can do individually to help reduce the pace of climate change, and he describes a survey that shows most people are just waiting for someone else to do something about it.

That rings true!

Here’s the video, watch it, then scroll on down and read my personal take on, ‘What can I do?’ I believe we can have a large impact – if we all pull together.

What can I do?

I’m going to share one idea with you, something I’ve been doing for a long time now, and something I’m finding quite easy that also makes a big difference. Just remember though, this one idea is just an example. Maybe you can think of something in your own life that you could change that would also have a useful impact.

I used to shower every day, after all it takes less time, water and energy than having a bath and that has to be a good thing, right? Well, yes.

But for a number of years now, I’ve made a point of showering once every two or three days, turning down the water flow, turning down the temperature, and also minimising my use of shower gel. I still enjoy my showers, the temperature’s warm enough to be pleasant, I’m not advocating cold showers!

So how does this help?

Much more than you might think. By showering less often I’m cutting my water use to less than half, and turning down the flow rate reduces water use by about half again. So I’m using only 25% as much overall. Turning down the temperature a little combined with the reduced water use reduces the heating energy required to perhaps just 20%. I only use shower gel under my arms and around the more personal parts of my body, cutting consumption by 50% or maybe a bit more. Combined with showering less often my use of shower gel is therefore down to 20 or 25% overall.

Bear in mind that shower gel takes energy to manufacture as do the plastic bottles that it comes in, as does disposing of the empties. Add in the energy cost of producing and supplying water, and of removing and treating the waste water, and it all begins to add up.

I hope this illustrates the energy savings that can be achieved by one, small change in one person’s lifestyle. And there are other benefits too. For example, my skin microbiome is probably more healthy for the reduced frequency and coverage of shower gel. If we all did this, and thought of other ways to reduce our individual energy use, we could make a huge difference.

Don’t just leave it to others. Work out what you can do – and make a difference!

The snowflake designer

I’ve always been interested in their symmetry, their beautiful shapes, and their infinite variety

Since I first saw a photograph of a snowflake under the microscope, I’ve always been interested in their symmetry, their beautiful shapes, and their infinite variety. But never had I imagined that it would be possible to create such snowflakes in the lab or control their growth to order.

Meet Ken Libbrecht, the snowflake guy. He began by investigating how they form, and can now build snowflakes more or less to order. Amazing! Watch this video in which Ken demonstrates his work to Derek Muller on Veritasium.

Ken has discovered so much about the conditions that cause snowflakes to form. He also understands the subtleties of humidity, temperature and so on that produce different kinds of snowflake growth, why they show the six-fold radial symmetry that they do, why they branch at particular places, and why individual ‘arms’ of a snowflake are almost identical to one another while different snowflakes are unique.

Evolution and behaviour

A computer program that simulates coding and inheritance on the one hand, and neural function on the other, permits the emulation of simple animal-like organisms

Today I want to share two striking YouTube videos that I found recently. Maybe you’d like to watch them yourself.

Introduction – The animation shows the molecular structure of DNA, rotating so you can visualise it more easily. Watson and Crick famously published this structure in April 1953.

DNA contains the genetic information that specifies the nature of plants, animals and other life forms. Each species has it’s own form of this DNA ‘instruction book’. Amongst other things, a species’ DNA controls the basic structure of the brain just as it does for other body parts. But here’s an interesting fact: The coding and behaviour of DNA can be simulated by strings of characters stored in a computer.

Brains involve cells called neurons with connections between them, and neural networks running on a computer can behave in a similar way to a very simple brain. Building a computer program that simulates coding and inheritance on the one hand, and neural function on the other, permits the emulation of simple animal-like organisms, and there are applications out there that do just this.

First example – One such program is Minute Labs’ Evolution Simulator (check out their YouTube to see it in action).

Second example – Another program, and I want to focus mainly on this one, is from David Randall Miller. He wrote a particularly fascinating simulator, see his YouTube demo and explanation below for some quite deep insights. It’s a long video, but breaks into logical chunks for easier viewing; I suggest viewing the first section and continuing if it seems interesting.

It’s a really helpful approach for anyone wanting to better understand evolution. It assumes only fundamental levels of the topics, but will enhance your appreciation of maths and computing while also demonstrating the basics of genetics, inheritance, simple neural networks, and animal behaviour. That’s quite a lot of benefit from just one video!

Some questions to ask yourself…

What new understandings did you gain?
Did you disagree with anything?
- If so, why?
What conclusions did you draw about the nature of living things?
Was anything surprising to you?
What questions do the videos cause you to ask?

Another way – write.as

The focus moves from advertising, costly payments and central control to an absence of these things

There’s more than one way of doing most things, and write.as is an alternative way of writing stuff online. Whether you want to create a blog, a story, or just private notes, write.as is well worth a look.

It’s part of a long standing move by some web users away from the commercial world of Google, Facebook, Twitter and so on, towards a very different model of which Wikipedia is the best known example. The focus moves from advertising, costly payments and central control to an absence of these things.

If you like freedom, privacy and simplicity, you’ll find all three at write.as . I suggest you take a quick look around, you can begin with a simple page I put together in less than five minutes – write.as/chrisjj

Marble Machine – Wow!

What an amazing device

I came across this marble machine today, somebody posted the link to Mastodon, I watched it once, and absolutely had to write about it here. What an amazing device. It does lose its marbles – well, a few of them anyway towards the end.

The astonishing Marble Machine

What is Mastodon, I hear you cry? It’s sort of a bit like Twitter, but is an open, free and distributed system. Wikipedia, the fount of (almost) all knowledge knows what it is. (Wikipedia even knows about the Marble Machine.)

Falcon 1

Things have come a very long way in less than 12 years!

Here’s a bit of history for you – SpaceX’s Crew Dragon vehicle is currently docked to the International Space Station (ISS) having safely delivered two NASA astronauts, bringing the number of crew on the ISS to five. The rocket used to put Crew Dragon into orbit was SpaceX’s workhorse – Falcon 9.

But you already knew that, right?

Well, on 29th September 2008 I posted an item about SpaceX’s first successful launch to orbit using their Falcon 1. Things have come a very long way in less than 12 years!

In the next few days I’ll try to write a piece about SpaceX’s Crew Dragon flight – watch this space (pun not intended).
