This isnt 2010 anymore bro. All the young kids are growing using PCs/Laptops since their favorite content creators, influencers and streamers are on PC. Also they love making/editing music, videos, photos etc. for which you need PCs/Laptops.
Gen Z and Alpha are coming from behind with an attachment to both mobile and PCs and the "core" millennial audience that was mostly on console is aging out of gaming, yes slowly but it is getting there.
This mentality of coming from work and not wanting to stay at a desk on pc is so 30, 35, 40+ year old opinion, just cause your son is like that doesnt mean he is not an outlier. PC is the hottest it has ever been, in max 2 gens, consoles are done, except gimmicky stuff like switch. It is a relic of an ecosystem, a closed ecosystem and people desire more from their devices.
