I don't think this means skynet apocalypse. I think this means most people will be out of a job.
A lot of people on HN take a lot of pride in thinking they have some sort of superior programming skills that places them on the top end of the programming spectrum. ChatGPT represents the possibility that they can be beaten easily. That their skills are entirely useless and generic in a world dominated by AI programmers.
It truly is a realistic possibility that AI can take over programming jobs in the future, no one can deny this. Does one plan for that future? Or do they live in denial? Most people choose to live in denial, because that AI inflection point happened so quickly that we can't adapt to the paradigm shift.
The human brain would rather shape logic and reality to fit an existing habit and lifestyle rather then acknowledge the cold hard truth. We saw it with global warming and oil execs and we're seeing it with programmers and AI.
