If you mean it would be dangerous in that it can improve itself beyond our ability to understand, contain, or mitigate it, then possibly.
If you're scared of it copying itself and then having multiple existing copies at once, then not necessarily. In that case it would be competing with itself for computing power and bandwidth. Look what happened when bitcoin forked - it lost a bunch of silicon time.
(Cue conspiracies about Bitcoin actually being a hugely powerful general AI disguising itself as cryptocurrency...)
I'm consistently amazed at how doctors aren't required - at least in Australia - to talk about side effects or withdrawal symptoms when prescribing medication. I'm capable of googling things, but it shocks me how none of this has ever been discussed with me when getting medication. Pharmacists will ask you questions to determine any contraindications, but I've never been spoken to about withdrawal or side effects. Half the time people find out about them by experiencing them.
Treat anything unambiguously threatening, and just keep an eye on anything else.
