I think I will be fine, thanks. I'll stick to my shell scripts, so far they've outlived any other devops fad.
Because I've seen my share of nasty "legacy" automation but, surprisingly, I still think a good set of well thought-out shell scripts written by someone that understands what's being automated still beat modern tools, even when the person doing the automation is the same.
I don't quite know why this is, but there's something timeless about shell scripts. I've also seen shell script automation survive for a long time unattended and with zero issues. Not so with some of the modern tools that are supposed to be all unicorns and rainbows.
