You are right of course.  But some quibbles: Digital is not "reparable," in the sense of an independent repair shop fabricating a replacement IC board.  What your repair guy or gal does is swap out a bad electronic component with a functional electronic component.  Those components are specialty chips and cards and when they are gone, they are gone.    In my M3, a competent machinist can fabricate any gear that is stripped in the the thing.    In any event, it is not the death of these chips you should worry about, it is the death and dearth of the ridiculous array of proprietary batteries, the "progress" from one proprietary form of TIFF file to another and the lack of meaningfully useful software interfaces to interpret the ones and zeros that these wunderkameras spit out.
Anybody remember the STN format?  It was the proprietary compression file structure invented/championed by Genuine Fractals (now Perfect Resize).  Here is what Perfect Resize says:
"
What will happen to the .stn file format?
Posted on September 5, 2013
The STiNG file support is provided in Perfect Resize 7.5 for opening exsiting .STN files for legacy users. STiNG is no longer a recommended format and this is the last release of Perfect Resize to support it. It is recommended that existing .STN files are converted to a modern format, like JPG2000, which maintains the wavelet compression but is more compatible and is an industry standard. STiNG files are not readable by Adobe® Lightroom® or Apple® Aperture® or natively in the Perfect Photo Suite. The only way to open STiNG files is via Adobe® Photoshop® if Perfect Resize 7.5 or earlier is installed."
Hear that?  That's the sound of a file format going >PLOP< into the sea of digital history.  And that is what will happen eventually to every proprietary RAW format that there is.
Electronic consumer products don't become "classic" they become "landfill."
