So if you don't know what CI is, what does "I am someone in tech", mean? Marques Brownlee probably doesn't know CI is, but he's also in tech. Because if you by mean "I am in tech" that "I am a software engineer", and you don't know what CI is, then boy; I'd be worried for you.

"AI is in the cultural zeitgeist"

Within the engineering tech sphere, CI/CD have also been terms that have been standard for at least a decade now.

You would probably be rejected from most interviews at the first stage if you didn't vaguely know what they mean at this point.

Linears entire product is tailored towards software engineers/engineers in general or people who work alongside engineers, so its not surprise their posts have a bit of assumed knowledge.

CI -> Continuous Integration

Its best thought of as the testing systems that are run as part of pull request review / merge to main / build processes.

Man, what a weird thing to complain about.

Most days I feel like I must be the dumbest person on HN. I don't understand what 80%+ of submissions are about. But if it sounds interesting, I'll dig into it a bit and learn a few things along the way.

I recommend making a habit of googling or asking AI about terms you run into. As someone who is in tech, you will hear tech jargon your whole career that will not be explained if it's considered standard terminology for the audience being spoken to. It is better to learn to educate yourself than expect others to go out of their way.
