Well, yes.
Mechanical cameras: can be repaired, assuming availability of skilled labor and parts.
Electronic cameras: repair options are limited to minor defects.
What's often left out of the equation is that many electronic cameras have been working for decades without any form of maintenance or repairs. Mechanical cameras are a different story.
The move to electronics in many industries was not just to push more extensive functionality (although that certainly was a large part of it). Reliability had a lot to do with it. The same with cars, but many people still have lots of trouble wrapping their heads around that one.
To each their own, in the end. I can sort of see the romance of mechanical cameras. But for actual use, I really, thoroughly enjoy the dependability of e.g. my EOS cameras.
Eventually, all the cameras will be broken and the only hope will be to fix them.
With a bit of luck, but that time there won't be any film to shoot with.
Since the argument is necessarily limited to smaller formats than 4x5/9x12cm, we can always go back to the dark ages of wet and dry plate for large format. That's a mechanical world anyway, and conveniently, we won't need any fancy shutters if we all go in plate photography regression.
