I remember ordering a free copy of the IA64 architecture book from Intel in the early 2000's(actual paper even!) thinking I was getting some head start on the future of computing(when it was clear that Alpha wasn't going to happen), but that never panned out. Clearly I've got a poor track record in guessing the path of CPU architecture(I even went 32-bit Core Duo over AMD64, once I got disillusioned over the idea of "better tech" winning out), so I'm still hoping that my buying an M1 Macbook Air doesn't doom Apple's move to ARM.
