The technology may be new(er) but it can be read by other drives that are NOT M-Disc ready.
I suppose some people are ok with ideas like, "use multiple platforms, brands, etc, etc.". I don't have time for that. I don't want to be a slave to transferring my media every 5, 10 . . . . ever. I just want to write it once and be done. Why should it be any other way?
Data rot is so prevalent that people have become conditioned to purchasing, repeatedly, new hard drives, new flash drives, more discs, discs, discs. The research is there about data rot, data degradation, data corruption.
The bottom line is, almost all optical media contains organic dyes. M-Disc does not. It has been ISO 10955 certified. The facts speak for themselves. Everything else is hyperbole.
As soon as the BR M-Disc comes out (not requiring a specific BR writer) I've got dozens of Mini DV taps and thousands of RAW images that will be permanently archived. Anything different than that is temporary, will require more time, and more money.
I'd like to hear what you decide on.
