Consoles exist because a dedicated custom gaming hardware is what's best for gaming.
Spiderman already running an open world with RT at 60 fps dynamic 4K on a $399 PS5 kinda shows it's the way to go vs general purpose non dedicated hardware.
"Best for gaming" is subjective. For me, the "way to go" is on PC. Doesn't mean I won't play on console, but I prefer PC for a variety of reasons. I agree there is certainly a better value aspect with consoles in the initial hardware purchase for most. But that isn't always the case. I'm going to own a PC regardless. So the difference between a non-gaming PC and a gaming PC can be as log as the cost of a console.
