I think the headline is correct, but the content isn't. Becoming the go-to person for the people with more authority than you is great. Becoming the go-to person for some people at or below your seniority level won't. Being the "python expert" who all the juniors ask python questions of won't help you, but if you can be in a situation where you frequently (probably informally at first) discuss higher level things with people above you and they value your input, I think that's a good thing. Get them used to the idea that they can go to you for input on important higher level things.
