recently a new collegue started to work for the IT company I work for. He seems quite polite and nice but when it comes to lunch time he very often brags and - for lack of a better word - talks utter bull****. He does this to a point where his statements become cringy, like:
I rarely use RAM anymore because SSDs are nearly as fast these days.
I run my virtual machines on my GPU only, because they're faster than CPUs.
I could easily hack this WiFi network but just don't do it because it's illegal.
(It was a WPA2 secured WiFi).
Basically he seems to have no clue about technical background but claims that he knows a shortcut for every problem. The problem is that he talks OBVIOUS nonsense and that EVERYONE knows it. My other collegues and I avoid him more and more but there's this awkward tension in the room when he comes around and brags again. When we ask about technical details he switches the topic pretty fast or answers even more nonsense.
My question is: Should we let him know somehow or should we just keep ignoring it? The team has never talked about it openly but there are many clues that everyone knows what's going on.
