Comment Re:Required signal strength ? (Score 1) 94

I don't think the eukaryotic cell was that difficult a transition. Consider mixotricha paradoxa, which is, essentially, the reinvention of the eukaryotic cell at a higher level. That only one germline of "eukaryitic-like" cells survived to the present isn't really a very good argument that in the deep past there weren't several. Most gene-lines eventually go extinct.

I don't think we have any reason to suppose that we're the only technological civilization within 300 light years. OTOH, within 4 light year the odds are quite good that there aren't any.

That said, I wouldn't want to guess how far it is to the closest other technological civilization...not without a better estimate of the lifetime of such civilizations. (My guess is that they're typically pretty short, but that it's possible to build enduring ones...but that this requires moving parts of the civilization into space in a self-sustaining manner.)

Actually, were the AI sufficiently good, I can see a large use case for voice controlled phones. But it would need to continue to work when the signal failed. And it would need to be able to recognize the voice of the owner when the owner had a bad cold. And to refuse commands coming from someone else.

That said, I think we're a bit distant from that level of capability. (Admittedly, I haven't checked recently.)

Actually, even 5G hasn't made it out to where I live, and probably to many other areas. So 6G is likely to take awhile. Mind you, they started charging for it a few years ago, and changed the frequencies used by the phone, so I had to get a new one...but they didn't get around to actually building the thing.

The reason that every major university maintains a department of mathematics is that it's cheaper than institutionalizing all those people.
