This whole situation reminds me of people's distrust for Big Pharma. Forgetting the actual problem and just assuming everything it produces is evil and will kill you. The problem with big pharma isn't that modern medicine doesn't work, it's that pharmaceutical companies charge so much for it that poor people are condemned to die preventable deaths in the name of profit.
The problem with AI isn't that it can't produce good code, it's that it's capable of producing a shitload of bad code at volumes no human can possibly review. It doesn't surprise me at all that the guy who made Linux can wrangle an AI to produce exceptionally good outcomes. The problem is that there's a million Joe Normals who are gonna try to replicate it with no idea how to audit the output.
