It is going to take at least five years before local AI is user-friendly enough and with performant hardware circulating, that ordinary folks would consider buying an AI machine.
I have a top-end DDR4 gaming rig. It takes a long time for 100b sized AI to give some roleplaying output, at least forty minutes for my settings via KoboldCPP with a GGUF. I don't think a typical person would want to wait more than 2 minutes for a good response. So we will need at least DDR6 era devices before it is practical for everyday people.
