Totally different infra: bitcoin these days is all dedicated ASICs that have basically no other use, unlike GPUs.

Hash mining asics don’t work well for AI

"don't work well for AI" is a hell of an understatement, the Application they are Specific to is literally just sha256(sha256(x)), what AI are you going to do with that?

GP probably didn't mean that hardware though, but rather the facility, electricity supply, cooling, etc.

Why double sha256?

The disappointing truth is that we simply don't know. Satoshi never explained it. For SHA-2 it can be used as a mitigation against length-extension attacks¹, and this seems like the most likely explanation, but it's just speculation.

¹ https://en.wikipedia.org/wiki/Length_extension_attack

Would length extension impact bitcoin? The messages aren’t secret afaik.

a that’s the botcoin hashing algorithm.

I figured that part out, I wonder why it's being doubled.

That was the way satoshi wanted it. No other explanation is known.

This is true, but large miners also have beneficial electricity contracts and data center capacity, both suitable for AI workloads.

the market is made up of many goods and services. Different people want different things at different times.

Article covers that briefly.

> The publicly traded miners have been adapting by diversifying into AI and high-performance computing, which offer more predictable revenue than mining bitcoin at a loss. Marathon Digital, Cipher Mining, and others have been building out data center capacity alongside their mining operations.

Yes, it does but lacks depth, the problem here is they are diversifying not pivoting and by virtue of game theory for each miner they stand to win on others exit, as the mining difficulty goes down, but this is creating a loss-loss situation.
