I don't talk about it a lot, but I am a long time #overclocker (started in 1994) and computer builder. Just a hobby, not competitive. Just, very long time.
The hobby is not dead, at all. But it is radically changed by the #oligarchs trying to get compute behind a paywall as Moore's Law grinds down. (That is "#datacenter" and "#AI" to most of you.)
Here is what you need to know: #truenas, #xigmanas, #openwrt, #pfsense, #openmediavault, switches, routers, and parallelism. And #thermalpaste.
