Just sticking to the hardware predictions, I am unsure if things will really go as planned. The thing with classical computing is that it's an easy-to-understand model, compilers and programmers can both produce good code for it. Predictions that simple, core-parallel processors will sweep away clever, ILP-based processors have been big failures historically, and I expect that to continue. The end of garbage collection also seems a step too far. It, like our current processors, is good enough that radically different successors are unlikely to succeed.

EDIT: I should clarify this is for general-purpose architectures. For domain-specific purposes, we definitely are seeing new, weird designs pop up. I liked this breakdown of the 'Dojo' architecture, to give an example: https://chipsandcheese.com/2022/09/01/hot-chips-34-teslas-do...
