Robots get smooth moves
Life, James Hein, Published on 25/03/2026
» The subject of the week is robots. The amount of news on these keeps growing and growing. South Korea is first up here with their KAIST Humanoid. In the field test, the robot was shown running across a soccer pitch, jumping, taking shots on goal, and even doing dance moves akin to the Michael Jackson moonwalk. Many robot demonstrations still look a bit stiff but these moves were quite smooth. The robot can run at about 12kph on flat ground with the next goal at 14kph. It can climb a ladder with 40cm steps and the knees can generate 320 Newton metres of peak torque so it can push heavier objects. The current model is based on the lower human half but the goal is for a full humanoid form that can work with people in industrial environments.
Sabine has the science you're after
Life, James Hein, Published on 08/10/2025
» Sabine Hossenfelder is one of the people I regularly watch on the YouTube platform. She is a physicist but also veers into other areas such as artificial intelligence and quantum computing. For her latest video -- In Which I Lose Faith In Quantum Computing -- she makes a number of interesting observations. In short, apart from some very specific applications, quantum computing, even if it is scalable from current technology, has limited application. It also has the potential of bringing down a number of current companies highly focused on this technology, or at least some of their divisions. Artificial intelligence takes up a lot of the space that quantum computing could do well in, but for the present at least, AI does it better. The next 10 years, or less, will be important to see how both of these directions develop, or not. If you are interested at all in physics, maths and occasionally quantum computing, then Sabine Hossenfelder provides some interesting perspectives.
Online Safety Act is a bad joke
Life, James Hein, Published on 13/08/2025
» The UK now has their Online Safety Act (OSA) and Australia is blindly following in their footsteps. In the UK it didn't take very long for the tech aware under-18s to bypass all the rules and regain access to adult content. Think about it, if China can't completely block everything do you think the UK had any chance? There were some creative solutions but the most common was a simple Virtual Private Network (VPN). In related news, some VPN companies reported a 1,400% increase in sign-ups since the OSA came into force.
LLMs are left-leaning models
Life, James Hein, Published on 07/05/2025
» A while back I wrote about the political bias in Large Language Models (LLMs). Since then the models have evolved and David Rozado has conducted more recent tests based on four of the popular political orientation tests. Using the Political Compass, Political Spectrum, Political Correctness and Eysenck tests, he worked with xAI Grok 3 beta, Google's Gemini 2.5 pro, Deepseek V3, OpenAI GPT 4.1 and Meta's Llama 4 Maverick. In all but one of the tests Grok 3 was closest to the centre, and on average was the clear leader. All the models were still located in the Left Libertarian quadrant, with Grok just sneaking into a more Conservative area with the Eysenck test. These tests are of course but one way to measure the political leanings of any LLM. Overall however, it does still indicate the left-leaning bias in all models tested so far.

What is an AI PC?
Life, James Hein, Published on 19/06/2024
» Last week I suggested that you would need something like a PC to run deep AI on your device. At Taiwan's recent Computex, there was the claim that they will sell tens of millions of "AI PCs". The problem is that the definition of an AI PC and what specs it needs is still vague.
The future of AI is LAM
Life, James Hein, Published on 14/02/2024
» After my earlier article, I realised I was somewhat scant on what a Large Action Model (LAM), also called Large Agentic Models, are. As already mentioned, these have derived from the Large Language Models (LLM), or what people now refer generically as AI, discussed before.
Graphene semiconductors mark new start
Life, James Hein, Published on 17/01/2024
» We have just started 2024 and there are already exciting announcements. The clever people at Georgia Tech in Atlanta have built the first scalable semiconductor using a graphene base. Graphene, a wonder product, is not a scalable semiconductor on its own, so they bonded silicon carbide, or what we call carborundum, to a layer of graphene creating the necessary bandgap to have a working switch. A switch means binary and from there they can make wafers like those currently used in the chip manufacturing process to make CPUs and other devices.
What would you do without internet?
Life, James Hein, Published on 12/04/2023
» India recently blocked all internet, phone and SMS access to the state of Punjab for four to five days as they search for a Sikh separatist. I had a friend who was there at the time and they told me how eerie it was to see no one on a phone for a few days. Someone would occasionally pull out the phone to see if service had returned but apart from that, there were no people talking loudly on phones in restaurants or on public transport. This impacted 27 million people, which is more than the population of Australia.
When AI is not smart enough for the job
Life, James Hein, Published on 14/09/2022
» I was wondering what to write about this week and then I saw the Japanese Amazon story and how it relates to artificial intelligence. Labour unions in Japan have been a thing since World War II, but delivery drivers for Amazon Japan were not unionised, until recently.
Metals and energy shortage is a looming threat
Life, James Hein, Published on 20/07/2022
» I know the word rare gives it away but the world is facing a rare earth metals shortage. The Chinese are currently the largest producers of this resource and they recently cut their production by half. Turkey is another potential source but that region has been unstable for centuries. Most modern technology cannot expand further without these resources and the whole idea of ramping up renewables requires lots of them. Elon Musk has said we don't have enough in the world for all the plans of our governments and other experts agree.
