I agree with the other comments. I'd add that just because the end product can be easily seen to be a complex mechanical artifact, doesn't make it inherently more complex to manufacture than something solid state. A lot of complexity goes into making the solid state device too; it just happens out of sight in the fab.

It's (somewhat) the same situation as with EV and ICE automobiles. The engine and drivetrain in a modern ICE vehicle is extremely complex. Much more so at a macro level than EVs. But we're actually pretty good at building reliable complex mechanical systems. More things shift to solid state over time but it's a long process.
