I don’t like commercial “AI” period.
That said, I did find some use for chatGPT last year. I had it explain to me some parts of Hawking’s paper on black hole particle creation, this was only useful for this one case because Hawking had a habit of stating something is true without explaining it and often without providing useful references. For the record, chatGPT was not good at this task, but with enough prodding and steering I was eventually able to get it to explain some concepts well enough for my usage. I just needed to understand a topic, I definitely wasn’t asking chatGPT to do any writing for me, most of what it spits out is flat out wrong.
I once spent a day trying to get it to solve a really basic QM problem, and it couldn’t even keep the maths consistent from one line to another.
Probably proper knife skills. I’ve always been pretty good with a knife, but I’ve been taking my time to really refine the skill as I do a lot of cooking for large groups so speed is extremely useful. I honestly learnt a lot of it indirectly by just watching how chefs use them, but for the details I started with Lan Lam’s video on knife skills over at the America’s Test Kitchen yt channel.
I’m about to be going to an event where I’ll be cooking nearly a thousand meals a day for three days, so I’m going to be putting it to the test. The one nice thing is we’ll have a team of volunteers to help with ingredient prep, so it should be okay but daunting none the less.
