There are two rationale objections, I think...

One is the potential for skill rot where AI grows a heavy dependence in new employees and once the real price per token cost is settled on and discoverable (post massive IPOs and probably a while post - not immediately after) we, as a society, are left with a bunch of people dependent on a deeply inefficient technology to maintain software we now view as vital that might severely impede our ability to actually deal with climate change (press X to doubt Bezos).

The second is that the psychological damage of interacting with models in a social context during your formative years is deeply damaging and we've essentially destroyed the ability for a generation or two to actually interact as productive members of society.

Addressing the second issue doesn't necessarily exclude our ability to leverage models for business productivity but it seems unlikely to happen in the current climate without that also happening. I am hesitant to believe in a sudden outbreak of common sense at this point. The first point, could really be a systems collapse trigger - we can argue about the likelihood but denying it as a possibility is excessively naive.

Both seem to just point at the WALL-E outcome, summarized as humans outsourcing too much thinking. I just don't see that as an end- just another divide between people. I'm seeing some degradation for sure, but not really an "end".

What climate change have to do with anything?

I agree with the skill drain argument but also think its a little too dramatic. Most people still can do the shit claude does for them, it just takes them 10x as long.
