I don't think this is a healthy attitude to have towards less experienced developers. Literally every experienced developer was once inexperienced, and I think for the vast majority of people, it's hard to become a senior or even intermediate developer without some mentorship along the way.
I believe this is especially true for aspects outside of writing code. This probably isn't true at every company, but from where I've worked, a big part of being a senior engineer is understanding how to tie in business goals to development. That's not really easy to learn in a tutorial online or by contributing to open source.
Anyway, I would just take caution when writing comments like this, and realize that in order for our profession to live on, we need experienced people mentoring inexperienced people. You were there once upon a time, and you probably wouldn't have liked it if people called you a "shitty college grad" and refused to help you out.
