I'm also wondering what kind of threat this could be to PoW blockchains.

What happens if AI doesn't pay off before the GPUs wear out or are in need of replacement?

So at that point a DC replaces them all with ASICs instead?

Or if they just feel like doing that any time.

Some chains are designed to be ASIC resistant.
