Look up Dr. Ronald L Mallett. This astrophysicist has some interesting takes on practical time travel. There’s a great interview with him by Fraser Cain of Universe Today.

AMD seems to be eating their lunch in small computers for consumers with their APUs in the Steamdeck and the more than a half dozen like handhelds, mini-pcs, etc. I’m sure intel will hang onto small embedded devices for industrial applications for some time but it’s puzzling that they would just drop RISCV which seems poised to proliferate in this sector as well. It could just be that intel seeing that manufacture in China is and will continue to be very tricky has to narrow focus while they move their manufacture closer to home.
