It’s an initial proof-of-concept. It’ll be developed into more complex games eventually, that’s not really an issue for it
Except it is an issue, just one being masked by the mountains of cash these companies are burning to provide AI. To increase the depth and complexity and actually store state would require orders of magnitude more energy, compute, memory and storage. The AI bubble is causing very single one of those to become more expensive. At some point the market will call bullshit on these companies (“show us profit, or at least exponential revenue growth, or line go down”), at which point these companies will attempt to download the costs onto their users. When people see the bill and realize what these services actually cost, the whole thing is gonna collapse like a flan in a cupboard.
