There's no NEED to move on from 1080p, but there are a lot of reasons.
I wouldn't even object to his position on 1080p if he said "the RX 5700 is fine for most users, don't waste your money and reduce e-waste".
He's telling consumers that they should expect to pay a premium price to be playing a slightly better than 2019 experience until 2028 or 2030. There are gullible people who won't understand that he's selling snake oil.
No, I expect him to gaslight naive consumers. Which is what he did. I just don't get why others are defending it.
In this case, at 1080p it's barely more performance for a lot more money. And if we're falling back on "good enough for most people" then an RX 5700 or 6600 is also "good enough for most people".
It's a free market, he can sell a low value product to suckers. That's his right. You're free to defend him and think it's not scummy. But it's scummy, and hopefully most people who know better are going to call it out.
