This. In the cases where I've been welcoming new individuals into teams it has always been made clear to them by me that there are no stupid questions, everything can be challenged if the argument for it can be made and that I don't know everything and wont/can't come up with all the ideas (ie they could very likely come up with a good idea to a hard problem). In my experience this has really made it a pleasant experience to introduce new developers (fresh from uni or new to the code base/domain) to the product and team. Just for context, in the country I reside in there isn't this emphasis on titles in the software space, and as such I am not a formal senior dev at my company. I believe I would have that title if living in a country where such distinction were normal.
