Zero hostility toward developers at all. All new languages are useless when they first start out (for varying definitions of "first start out").
As for why, I tried switching some of my easier Perl5 scripts to Perl6 a few years ago, and they got a little shorter and a lot harder to read. I loved Perl5 -- it's hard not to like a project that puts you in the authors file for a few patches -- but Perl6 appears to be going in exactly the opposite direction than I would choose. That plus the perpetual vapor makes it awfully hard for me to find a use for it.
I'll close with the hopeful sentence at the end of my comment from 4 years ago: https://lwn.net/Articles/330101/ Though, I've tried Perl6 since then, and I'm less excited about it now.
