How could an AI "escape the lab" ?

I see a ton of youtube baitclick videos with hundreds of thousands of views talking about an AI that tryied to "escape the lab" But that's a terribly stupid idea no? How could an AI "escape the lab"? It would host its entire code on a cloud with a console able to run commands? Like how would that even work? This is just not possible right? I saw so many of those clickbaits that I want to understand why this is dumb Or maybe I am the one who's ignorant and if that's the case I'd like not to be anymore! Waiting for someone way knowledgable than me on the subject to explain it to me if.
