How do really talented people in academia think about people who are less capable than them?
I wouldn't say I'm a 'top' professor - hopefully someday, heh - but here's my take on it.

I couldn't care less how 'smart' my students are or aren't. It's tough to quantify, and different people have different strengths, and it's easy to mistake knowledge/experience for intelligence. At any rate I feel that my job is the opposite of competing with my students in any respect. I want to help them do well in (class/research/etc.) and find it all interesting and rewarding.

I always urge my students to ask me for help if need be, because:


I do try to explain things well and clearly, but I don't always know if it totally gets across
All of my students are different in a gazillion respects, meaning that they're not all going to understand the same things easily
Providing extra assistance is part of my job!


I tell my undergrads that someone who has gotten an A in my class and gotten lots of help from me deserves that A exactly as much as someone who has gotten an A in my class with no help. Everyone is entitled to my assistance, even on a weekly basis or whatever. I don't think poorly of students who request extra assistance. The course is meant to have my students learn a thing or two; if they're a bit confused, I'm more than happy to clarify. The students I worry about the most are the ones who could benefit from extra help - which all of my students are permitted to seek whenever they'd like - but who haven't sought it out!

The only students I actually get at all impatient with are the ones who show indisputable signs of dishonesty or implausible excuse-making or picking on classmates or whatnot. Those ones irritate me. The rest are a joy, whether or not they seek extra help.
