Well "sad" is, of course, entirely subjective.

I personally don't give a shit about Java or MySQL, so I wouldn't have been sad if those products died, but I know lots of people who would be.

For me, it was ZFS that I was really excited about. Back then, I thought I might have ZFS (or some ZFS-derived or -inspired equivalent bitrot-resistant checksumming filesystem) on all my computers and phones by, say, 2017.

But I don't. My Linux box can finally have ZFS (with some caveats), but my Macs and phones can't and won't; it was another sad day (for me) when we learned Apple's "modern" new filesystem, APFS, does not do checksumming for user data[1][2].
