I see, so when pursuing future technologies we should stick with what we know? We typically research what’s achievable in the near future, however the mechanics for purifying heavy metals with centrifugal forces isn’t new fwiw. It’s how we made atomic bombs.
Tone policing is a weak retort. If you'd rather we just sing Kumbayah and talk about science fiction then yeah! We could even staff these centrifuges with autonomous bipedal androids a la Lt. Commander Data. Those are becoming attainable in much the same way as your mechanically simple, cost effective, never been built zero g metal gas centrifuges. Learn something with that big brain of yours.
No, I’d rather people just not be assholes but some are simply incapable of it.
I’d note you’re responding in a thread about asteroid mining becoming more attainable, at a time of large language models in the last two years being able to remarkably emulate natural language beyond anything dreamed of three years ago, with low earth orbit lift a commodity orders of magnitude cheaper as we work towards a moon base, in the final stages of preparing an interplanetary starship built by a privately owned company whose owner wants to personally colonize another planet, while humans are only years away from potentially being redundant at driving (and possibly many white collar professions)… and none of that was made possible by people with no ability to imagine a future like yourself. Enjoy your petty and cynical existence of insulting people on the internet while the rest of us make the future you were promised despite you.
