At least in my case, I don't think that's where the anger is coming from.
If LLMs were truly able to replace me, I'd be disappointed, sure - I've spent 30 years developing mastery of a craft, it's sad to see it go. But I'd resign myself and move on.
But that's not what makes me mad.
I get angry because I simply don't believe it is true. I have a reasonable math and tech background to where I grok how this stuff works at a fundamental level, and I'm utterly unconvinced that it is performing any sort of reasoning.
Call it a stochastic parrot, a token extrusion machine, whatever, but these things are not thinking or reasoning.
That doesn't mean they aren't useful- they clearly are very useful for many tasks.
My anger comes from the global attempt to replace things that require human reasoning with LLMs.
There's this push to use this stuff way past the point of "helpful accelerator" to "why do we need programmers/doctors/lawyers/etc..."
I think it's incredibly dangerous.
So while the tool is useful, I don't think we've figured out how to use it appropriately. For all the short term appearance of productivity boost it provides (whether this is real in a total-cost sense is still an active question), I think the risks to skill development and quality outweigh those benefits in many cases, and are being overlooked.
