I didn't mean GSOC are trivial. Apologies if I came across like that. My understanding is things approachable by students would be slightly easier compared to things approachable by someone working in the industry. Maybe my understanding is wrong.
I was referring to the entry barriers due to technical difficulty.
To restate with better terms, I believe that the GSOC projects have a generally high entry barrier, due to the fact the they require knowledge in the field. I think the students are hardly beginners.
However, I may be wrong. Something very interesting is that one can open the organizations for the past years (https://summerofcode.withgoogle.com/archive/2020/organizatio...), pick a project (ie. https://summerofcode.withgoogle.com/archive/2020/projects/62...) and see the detailed report ("GET THE CODE" button).
