That's a very pessimistic take. I recently sold a Sonos connect - about 15 years old if not older and working as well as when it was new. I have a Google home max speaker, 8 years old, works flawlessly. We have a pair of B&W speakers from 2001 or so - got the speaker insulation replaced, otherwise everything great. And a 5.1 set from Logitech from 2005 also works without issues - the difficult part is to only make sure the PC has the right outputs, but even that is moot with USB sound cards. We also have some cheap monitor speakers, they work fine after 7 years.
