Sorry if I got you on the wrong foot. I was merely generally rambling, not critcizing you personally or your point. Of course it's fine to discuss this, just like it's fine that people discuss pokemon or cool jazz (who am I to judge). I could have posted this anywhere in the discussion tree. I'm merely a little fed up when some tech folks make it sound like this should be top priority for humankind.
Of course you're right about the physics.
And I don't have solutions to the hard problems either. They are hard for a reason.
Ah ok, thanks for clarifying. I certainly don't think it should be a top priority either, partly because of the low subjective probability, but mostly because it would be an outside context problem (excession) - it's impossible to prepare for an event whose implications we can't bound
