Yeah. I left this out for the simplicity of the argument, but something we really didn't have a good idea of at the time (especially because it largely hadn't happened yet, and we might not have been able to measure if it had) was that climate change exists, and cars are a huge part of it.

We know that now, but are stuck in a world with cars, we're trying to dig ourselves out of that hole.

We know that crypto[1] uses massive abouts of power when we're struggling to move off fossil fuels. We know that now, at the genesis of the crypto.

[1] the crypto I care/talk about, the power hungry kind.
