I've often thought about how likely it is there are intelligent and sentient civilizations that are content to their planet, or bounded to it by - as you mentioned - physiological constraints. I never connected that to "you probably need hands or something very closely approximating a hand" but it makes perfect sense.

Intelligence is such a bewildering fixation too when you think about it for ourselves. Due to science fiction writers and our insistence on anthropomorphisation we assume we will be forming treaties aboard an alien ship meanwhile we have yet to communicate let alone form a treaty with any other form of life just here on earth. The hubris is massive and it invades even the scientific community to a degree. Whoever put…

> the idea that FTL communication/travel is difficult or impossible Not just FTL. My hypothesis is that any type of substantial interstellar travel is going to be so enormously expensive, complicated and time consuming, an advanced civilisation will only do it once in a billion years. In the form of mass exodus when there are no more habitable planets in their system or their star is going nova. As this never gives e…

But that's simply not the case. We likely very close to the technology needed to get tiny objects to a decent fraction of lightspeed using laser arrays. Assuming genuine AGI is possible and miniaturisation continues, there's no physical reason a digital intelligence couldn't rapidly (on interstellar time scales) colonise the galaxy.
