I think being dismissed shouldn't be a bench-mark for determining whether or not software engineering is for you.
The only benchmark should be whether or not you like software engineering and to really arrive at an answer, you should work in the industry for a few years, ideally 3 or 4.
I have been an engineer for 3.5 years now and I think I like it, which is why I continue to be in the industry. The day I don't enjoy doing it, that's the day I'll call it quits and figure another line of business out. :)
