They have some mechanical bits. I think you can fly the a320 by modulating the engine thrust and using trim wheels.

The more terrifying thing about airbus is that their philosophy (like teslas) is that the computer is the ultimate decision maker.

Boeing has the philisophy that it is the pilot (with a little caveat for the 737 max mcas thing)

Exactly.

In the case of the Cybertruck you can't modulate shit!

Not totally. They have two redundant computers in the control loop. But they worked out this was a shitty idea if there was a failure so there are mechanical and electrical backup systems. Whilst "fly by wire" technically speaking they don't involve a computer in the loop.

I'd still rather have a totally mechanical backup.

What's the basis for that claim? Even in direct-law, there's still a computer in the path. In aircraft with the BCM, that's still a flight control computer, albeit one that's separate from the primary/secondary flight control computers.

AFAIK BCM is straight servo loop.
