Consider not going on a modern airliner. Every commercial passenger jet since the A340 has been fly-by-wire. (military jets have been so longer).
737 Looks like cables, air, and hydraulics to me.

And magnets repel with an inverse cube law. So there is no simple way to replace a spring with magnets. You could "linearise" an electromagnet with distance sensors and code, but that's a bit of a Franken-Solution - not least because any delay in the closed loop could make the system unstable. In this case a couple of minutes of research - or maybe asking a physicist - would have saved a lot of essentially rather poi…
You coukd linearize it using a meta-material of small magnets, though it would probably end up being a cylinder lined with magnets of varying density.
Loved the video. Didn't love the loud beep near the end, that's at about 3x the volume of the speaker the whole video...
YouTube desperately needs an audio compressor feature. Can't imagine why they haven't implemented that yet, it's more or less trivial.
I’ve often thought it might be interesting to replace the springs in a piano’s action with electromagnets so you could have control over the exact touch profile.

Every link i’ve seen to this story annoys the hell out of me because they don’t explain HOW the elevator eventually stopped. That’s literally all I want to know.
I’d also like to know what they meant by “plunges”. How fast did it descend? Was it in free fall?
They should try this with electromagnets, and make the curve linear using electronics (and perhaps find the optimum curve in terms of fun when jumping around).
Wouldn't that consume a lot of electricity?
Unsurprisingly, an inverse-square mechanism can't replace a linear one over a wide working range.

But you have more time to react on a plane and switch to manual override. It's not like people fly with just a few meters distance to other airplanes. There's also a good distance to the only other thing you can crash into, the ground, as opposed to driving between walls or with a cliff to one side.

About as scary as my Tesla on autopilot going around a curve at 75mph. Every time I ask myself, what if there is a bug or if it turns off...
Pretty much every critical system in a vanilla Toyota is already software-controlled, not to mention the legion of critical systems involved in air travel, elevators, medical equipment (e.g., pacemakers), etc. Not sure that this should bring comfort, but at least you need not be particularly frightened by your Tesla. :)
