I wouldn't be so pessimistic, Intel and AMD aren't going to stop making CPUs, and if their integrated graphics adds AV2 it will be motivation enough for others to follow.
Ram and Ssd is just the start capitalism dictates profits will suck all production to AI. CPu have 3-5 year production timeline ie cpu prices will start going up a lot more as previous production contracts expire you might even get shortages new consumer cpus won't be affordable or spread as fast as you think.
