No, it isn't. If you think it's "perfectly fine" to dismiss people's legitimate concerns and complaints by telling them to "suck it up", the problem is that you're an asshole, not that AI is unimportant or whatever it is you're trying to imply.
Ignoring your rudeness, the word "legitimate" is doing a lot of heavy lifting here. It would take me one second to present you with an issue that concerns me, that will make you say "suck it up" because you don't consider it a legit issue, and I would end up being the asshole in the exchange.
Does this hypothetical issue concern you AND the rest of society as a whole as well, or just you? Because there is a big difference between the two cases.
Those same people were callously telling factory workers who lost their job to automation and outsourcing to "learn to code"; they don't deserve any sympathy. Assholes are the hypocrites who are fine automating other people's jobs away but not their own.
