I totally agree with Linus Torvalds in that AIs are just overhyped autocorrects on steroids

Did he say that? I hope he didn't mean all kinds of AI. While "overhyped autocorrect on steroids" might be a funny way to describe sequence predictors / generators like transformer models, recurrent neural networks or some reinforcement learning type AIs, it's not so true for classificators, like the classic feed-forward network (which are part of the building blocks of transformers, btw), or convolutional neural networks, or unsupervised learning methods like clustering algorithms or principal component analysis. Then there are evolutionary algorithms and there are reasoning AIs like bayesan nets and so much much much more different kinds of ML/AI models and algorithms.

It would just show a vast lack of understanding if someone would judge an entire discipline that simply.
