That's a tale of saturation. Toaster sales are probably relatively flat as well. Not because toaster use has declined but because people already have a toaster that meets their toasting needs. PC improvements have slowed to a crawl over the past decade in terms of real-world performance gains for the average consumer. Their 5 year old rig still manages to surf the web, stream videos, play games and send emails just fine so they see no reason to upgrade. Another 4 cores or the jump from 14nm+ to 14nm++++ isn't justifiable for the average user. That said I bet the combination of COVID + AMD really coming out swinging the past 2 years might make for a bit of an anomalous spike.
