    The GP was just setting a lower bound of 1B to establish a basis for calculating the cost to move humanity offworld. The cost for 5B people or 7B people would be even more cost pro…

    If you liked the first one you'll probably like the second one too. It sounds like the GP probably hadn't seen an avatar movie before?

    So then they'd have formed on earth - no panspermia required?

    The wings on the thopters described in the novel by Frank Herbert were more bird-like than insect-like. I don't know which type, if either, will be more practical to build as mater…

    Is training with dropout still a thing? Does that mess this up?

    I think it's at least strongly implied in the movie that he has to work much harder than (for example) his genetically superior brother to achieve the same level of performance. So…

    I think you're both right. Introducing H2 as a fuel only helps matters if the energy used to produce the H2 is not from fossil fuels, and probably hurts otherwise. Right now the wo…

    I don't know what this LOHC stuff really is, but it's easy to imagine that dissolving H2 in in an existing liquid would be much less of an undertaking than inducing it to become C8…

    OS kernels tend to use them simply because they don't have malloc at their disposal and so it's most practical to stick to fixed size memory chunks, right?

    I'm glad you linked to that article, which I had not seen before. I think I agree with the author about degrowth as a goal being a political nonstarter. But I'm pretty skeptical ab…

    Are you sure it's not just that their hair and fashion styles are those of a previous decade and that that triggers the "this person is old" neurons in your brain?

    That assumes we're the object of the simulation rather than a byproduct. Maybe what they want to simulate is a universe and we've just happened to pop up in a small part of the sim…

    It's not the only important thing harming the biosphere and GHG emissions are not the only unsustainable human practice. But we are talking here about global warming specifically a…

    If we mitigate climate change, it will be through carbon pricing. So I support that. Mostly by giving time and money to [ https://citizensclimatelobby.org/ ], as I think their lase…

    It's just an english idiom that doesn't mean much. It's like saying "If you are looking for an honest response, the answer is no."

    I suspect the GP is interpreting "Honestly?" as an expression of incredulity at being asked the question - as though the asker did not know their place as an employee. I can see ho…

    This is interesting. Clearly _something_ happened in the early 70s (noise in the signal makes it hard to be sure of the precise year - if even there is a single discrete event). I'…

    What does it mean to be "backed by" carbon captured? Talk of backing a currency traditionally refers to some mechanism that guarantees people will continue to value it in the futur…
