"Chernobyl: a crazy design with a strongly positive void coefficient. No one else has ever made such designs, even before Chernobyl because it was always known to be dangerous."

Hmm.. which unit? not widely known, two meltdowns occurred at Chernobyl. NPP, Unit 1, September 9, 1982 and then the Unit 4 explosion April 26, 1986, which was hidden from world until the fallout trigger a Swedish radiation monitor.

Eight days days later, (May 4, 1986), a pebble fuel pellet got stuck in the piping in a German 750MWth, AVR PBM reactor. Efforts to dislodge the pellet caused a release of both core and coolant into the atmosphere. Local plant management tried to blame on the Chernobyl disaster. But a professor at a local university in Frelburg, analyzed the fallout which contained radioactive Pa-233 and determined that a second nuclear incident had occurred nearby.

So their is a list of three(3) incidents, each time management/government tried to cover up and there is much more.

Don't fooled, TMI unit II was only 4 months old when a valve got stuck and melted down.. Fukushima is the worst yet, three(3) fully mature reactor cores have melted down and now reside somewhere below the reactors, releasing deadly fission by products into an underground river flowing underneath it.

Millions of humans have succumbed to early death, and Ten's of millions more are suffering the consequences, and that is just the tip of iceberg. Their is nothing clean about Nuclear Power plants, each refueling cycle discharges a large amount of radioactive gas into the environment, and the effect is detectable in the surrounding population.

#4: There's massive amounts of stuff to do backups for UNIX.

That's odd.. I use Linux Mint/ddrescue to backup/restore images of Win OS partitions/disks all the time. WIndose doesn't have anything even close. I can even mount those NTFS file images as partitions and modify the contents as needed. Have you tried to mount a Ext-3/4 FS on windows lately?

M$ has a nasty habit stripping out long established features, obfuscates, cripples/breaks, and/or removes them, then monetizes it as a paid feature. I.E. Network users(>10,>20), Backups, SQL, Exchange, etc.. Meanwhile Linux/Open source rarely removes features and incorporates new features all the time.
