There's no way to win in these threads. It's a very common pattern on HN that somebody will say, "X doesn't exist!" And then people will proceed to point out that in fact does exist. And then you'll find out that the original poster has a bunch of non-functional requirements that were baked into their original request that they didn't state, and I usually don't agree with (typically because they are either not practical or only of theoretical concern). They'll typically defend them using highly charged language, like claiming that having to carry a 200 gram device will pull their pants down because it's so heavy, or that managing a Bluetooth stack and USB doesn't require an OS, but rather just a couple of event loops that a non-professional could code directly in firmware.

I've simply stopped participating because in my efforts to try to help people, I find that I just get into silly arguments.
