No, I actually think that is a good analogy. If you just want to have something up and running and use it, that's obviously totally fine and valid, and a good use-case of Docker.
What I take issue with is the attitude which the person I replied to exhibits, the "why would anyone not use docker".
I find that to be a very weird reaction to people doing bare metal. But also I am biased. ~30 Internet facing services, 0 docker in use ๐
AFAIK I'm neurotypical... No, trains of thought like these are common (see also other respondents on here), and they can also happen in the blink of an eye. It's just that when the question or comment has formed, I'll make a mental note to either ask/mention it later after the current topic has concluded, if I think the other person also has interest in hearing it, or to google it later if not. Or to just drop the thought if I come to the conclusion that it doesn't matter all that much to myself either.
(Actually, the only time I've been able to fully let go and scream while crying as an adult was when just so happening to be next to a torrendous river. I could not possibly scream loud enough to be heard by anyone. It is so freeing to just scream everything off your soul. 10/10 would recommend. Sorry for kinda off-topic.)
Cool idea. But since it doesn't seem to be open source and self-hostable, I won't trust it.
