No, there'll just be fewer big-budget games. Streaming is always going to be a sub-par experience (latency and video compression). And the mess that AI made of the hardware market has likely killed off (or at least indefinitely postponed) the next generation of games consoles

But we've got 4-5 decades of games to enjoy.

Part of the reason that the games industry is struggling is that there's been no real generational leaps for a long time. Gaming used to be driven by those technological leaps, but these days we just get incremental improvements. 10-15yr old games are just as entertaining as brand new releases and often don't look too dated.

Also, ever more people are getting into retro gaming, enjoying the classics from the 80s and 90s, from well before microtransactions and hyper-competitive online multiplayer.
