Dedicated hardware still has benefits, having your phone notifications separate from gaming, if your phone breaks having your console break would suck, and imo a touchscreen will never surpass physical buttons on controllers so you’d still want those.
I personally hope the future looks more like a steam deck than a gaming phone.
The 3% is a reason to be skeptical, but doesn’t necessarily refute the 99% claim. A person can be a Native American, part of their community, and have a grandparent who was an immigrant. 2/3 of them at minimum would need to have a similar situation at minimum, but it’s less than the percent who live outside reservations (78%) so it doesn’t seem totally far-fetched. It seems high though to be sure
