Nope. I'd still say social media/social media algorithms.
Imagine if social media didn't exist (beyond small, tight-knit communities like forums about [topic], or BBS communities), but all these AI tools still did.
Susan creates an AI generated image of illegal immigrants punching toddlers, then puts it on her "news" blog full of other AI content generated to push an agenda.
Who would see it? How would it spread? Maybe a few people she knows. It'd be pretty localised, and she'd be quickly known locally as a crank. She'd likely run out of steam and give up with the whole endeavour.
Add social media to the mix, and all of a sudden she has tens of thousands of eyes on her, which brings more and more. People argue against it, and that entrenches the other side even more. News media sees the amount of attention it gets and they feel they have to report, and the whole thing keeps growing. Wealthy people who can benefit from the bullshit start funding it and it continues to grow still.
You don't need AI to do this, it just makes it even easier. You do need social media to do this. The whole model simply wouldn't work without it.
Unfortunately, it's quite difficult for AMD and Intel to make any big difference in the short term.
On the Intel GPU side, bluntly, they are far behind in tech, so they have to mitigate that with more aggressive pricing.
Don't believe me? Look at the process node they use and the die size of their chips, now look at the performance and power efficiency they get compared to similar mode/die size Radeon or Geforce cards. That means Intel has to spend a lot more but can't charge anywhere near as much.
Intel doesn't make money from their GPUs yet. They literally don't want to sell too many cards because they generally lose money on each one sold. They're spending right now to build expertise and expertise before doing a bigger push later.
On the AMD side, there's some good news in that their latest generation is pretty great and has massively outsold their previous generations.
The bad news is that even if AMD has doubled sales or whatever, they were already such a small part of the overall pie that Nvidia (85%+ of the market) shitting the bed isn't something AMD can suddenly fix.
It'd be like if all carmakers except Mazda shat the bed, Mazda can't suddenly expand and fix the market.
Whenever there's excess demand for CPUs, AMD would also prefer to service that market. It's far higher margin.
