I mean, I hold the same opinion. Kind of like when compute was expensive in the 80s and early 90s, you weren't going to let something eat half your compute without noticing it.

But I don't see this being a barrier that lasts. With compute getting faster and more of it, along with algorithmic efficiency increases at some point we'll end up with a world that looks like ours now with CPU compute. There's plenty around to buy, borrow, and steal.
