Steam

There are only a finite number of easily purchasable game dev assets out there

So? There is an infinite ability to reuse these assets over and over. You dont need fresh assets to create a shitty game.

AI struggles to make a complete, composite product. This is the limit on game creation as it is anyway, not number of assets available to steal/download/buy. There are thousands of options for near-complete games out there that can be easily customized further with the millions of art assets out there as it is.

Even then, Steam isn't completely without moderation. It's been possible to automate the creation of asset flips for a while (and we've seen it done plenty of mobile), but Steam makes some effort to remove the lowest quality games and make it ineffective to publish low-quality shovelware. AI is still quite a ways off from being even remotely faster or more effective than just buying a template and filling in the resources with cheap or free assets.

Why take already created assets if you can generate everything the way you want it? I found lumalabs.ai yesterday wich makes text to 3D. Right now it could be a good base for someone to generate an idea of the final product and then have a 3D artist re-do them in more details for the final project or just clean them up a bit.
