Everyone I know with quality speakers has them for decades. If they don’t remain the primary system they’re used as secondary.
Bluetooth support may end much earlier but there should remain a wired option. Treating speakers as disposable counteracts my reasoning for spending lots of money on them in the first place.
My main sound system is composed of JBL S-34s and I've had them since 2000. Nothing beats a plain speaker with + and - terminals on the back.
This is one reason I'm sad that the Airport Express was discontinued. You could use it to give AirPlay support to any sound system, even something vintage like a Pioneer SX-780 receiver.
