That's a fairly common "playing both sides" argument. Productivity+++, but really nobody needs to worry for their jobs. These things are not likely to be true at the same time.

People are saying that AI will transform the way we teach and learn. It has already transformed the way students cheat and, to my surprise, how they apologize for cheating.

 Analyzing 2M papers published immediately following the training of five prominent open LLMs, we show that ... the most perplexing are disproportionately represented among the most celebrated ... and also the most discounted.

It's an interesting question what "the fundamentals of programming" are going to be in an AI age. Two months ago I would have agreed that being able to program yourself, without AI, line-by-line, will remain crucial for the foreseeable future. Today, I'm much less sure.

The reporting on the tragic ChatGPT suicide assistance story triggers me a little bit, but not in the way you might expect. Teenagers turning to ChatGPT in times of crisis was bound to happen, given that mental healthcare everywhere is expensive, unavailable, and of embarrassingly shitty quality.

Many decision processes end up unfair because for the deciding body false positives are disastrous but false negatives are almost irrelevant. That's how you end up with coding interviews, overreaching visa requirements, and similar.

If there is one modern word I can't hear anymore, it's "cancel culture". Can we please stop pretending like there was ever a time where you could just say whatever you wanted and people did not react to it (up to and including putting your reputation on blast in whatever media existed)?
