Uh-huh.

It's worth keeping in mind that we are here talking about people who simply will not be satisfied until they have built Skynet[0]. They will then no doubt experience some very brief satisfaction before we are all annihilated.

I can't help thinking the juice isn't worth the squeeze.

I'm not sure what the alternative is or how to change course unless and until it becomes unambiguously apparent that such a thing is not possible. Currently it seems like we still think it might be possible, so that's where we're heading because if "we" don't do it, somebody else will.

[0] How feasible this really is, or on what timescale it might be possible, I don't think anyone can really say. But, at least for now, this is clearly the aim and trajectory we are on.
