Having diversity in the computing ecosystem is a good thing, not bad.
I'll take your point that Docker brought containers to the developers (frankly, I made that point myself) but that doesn't mean that Jails doesn't solve some problems that Docker (currently) struggles with. Nor does Docker's success mean that a little competition isn't healthy for the wider industry.
Dismissing the stuff that went before it as "systems administration garbage" because it was targeted at a different audience to yourself is a really poor attitude in my opinion. Especially when there are countless examples of when audiences different from developers also need to make use of software. Frankly, I thought by now we were past the sysadmin vs developer flamewars. But clearly not.
Aside from that minor rant, I do want to thank for your post. It was an informative read.
