The M11 is electronic- and electronics die. Basic components stop working. Specialized components like the onboard processors get EOL "end-of-Life". Twenty years- we'll see how many still work. If the electronics need to be replaced, that is a major problem.
You should watch Curious Marc's channel on YouTube to see just how long old electronics can be made to last, if somebody is determined to do it. Doing component-level repairs on a circuit board or emulating an old custom processor on an FPGA isn't any harder than, say, winding new springs for a M3's shutter curtain rollers -- it just requires a different kind of specialist. The difference is that nobody right now cares enough about old electronic cameras to make it worth the bother. That might change.
