Just because an AI seems to know finance/architecture/debugging doesn't devalue authors knowledge of said domain. Its essentially like your coworker having the same knowledge. There's space on the market for both. And if AI gets to the point that it can in fact replace engineers (somehow also claiming accountability?) I'd expect it to be priced competitively enough to make every manager think hard whether to buy and become hopelessly dependent on some 3rd party service or hire an engineer. The market is not a zero sum game.

Nevertheless new maths is exciting and might lead to what I find slightly more interesting - new physics.

The productivity increase religion has never really been about workers. Any increase in productivity is used to reduce the workforce count and to bleed dry existing workers who now have to overproduce in place of their fired coworkers. Its sad how occasionally some people obsess about their productivity on HN as-if they're unaware that they're buying into the very thing that will get them fired and/or burned out.

Also I suggest giving it low-level instructions. Its half-decent for low level stuff especially if it has access to preexisting code. Also note that it does exactly what you tell it to do like a genie. I've asked it to write a func that already exists in the codebase and it wrote a massive chunk of code. It wasn't until after it was done that I remembered we already have the solution to the problem done. Anyhow the hype is unreal so tailor expectations accordingly.

I also find it kind of funny that the only perspective on AI is about being laid off. This says a lot about who's writing all these articles. But beware the cobra effect https://en.wikipedia.org/wiki/Perverse_incentive . If the AI boom allows a company to lay off a large amount of its engineers the engineers can also simply band together and as-easily become a competitor unburdained by legacy code resulting in profits going down for existing businesses. Alternatively they can simply join the customers of various SaaS businesses and roll their own solution with same net effect.
