Given rcxdude’s reply it appears I am one of those humans who can’t figure out special relativity (let alone general)
Wrt ‘AGI/ASI’, while they’re not the same, after reading Nick Bostrom (and more recently https://ai-2027.com) I hang towards AGI being a blib on the timeline towards ASI. Who knows.
But I'm so used to AGI being conflated with ASI that it didn't seem worth it compared to the more fundamental errors.
