Thing is, the Internet at its core is just a vastly interconnected network. That’s it. All the effects of the Internet are direct consequences of that fundamental property, and time.
The technological architecture that supports the complexity of modern civilization? The direct consequence of interconnectivity × time. QAnon? The direct consequence of interconnectivity × time.
You can’t restrain the bad without crippling the good.
I think humanoid is a perfectly logical end-state for any terrestrial species that develops technology:
Gotta get energy somehow, consumption is more energy dense than autotrophy, so need a mouth. Gotta find the stuff to put in mouth, so need sense organs, closer to mouth is better. Light is generally the best medium for sensing, so eyes eventually. Two eyes are way better than one for depth perception, but three is inefficient energy investment with seriously diminishing returns.
Gotta move around in a gravity well to get to your food, so you need some kind of limbs. In the beginning, before developing the sophisticated nervous system necessary for dynamic locomotion, four is the minimum so you can remain stable on three limbs while you move the fourth.
Gotta start banging rocks together if you want tech, so you need hands of some kind, and two free limbs. By this point, your nervous system should be sophisticated enough to allow dynamic locomotion, but you still need at least two “legs” to move relative to each other to move on the ground in a gravity well.
I would expect most technological species with similar heritage to humans to look roughly humanoid. There are plenty of other forms, but I feel like they’d be selected against.
Same. I figure out the most efficient way of doing something, and do it that way every time forever. Until I learn a more efficient way, which becomes the new way I do it forever.
Primer and The Man from Earth are two of my all time favorite films. Production value is nice and all, but an interesting idea explored well wins every time for me.
My favorite movie about time travel is Back to the Future, but the movie that I think did time travel best is Primer. If time travel works, it’s probably like that.
