“The (academic) universe is a dark forest. Every civilization (professor / grad student) is an armed hunter stalking through the trees like a ghost, gently pushing aside branches that block the path and trying to tread without sound. Even breathing is done with care."
Profs and students would poach ideas, submit before the research was even complete blatantly violate double-blind reviews, and submit to multiple venues in parallel (a huge no-no in academic publishing).
Arvix is the only silver lining on that cloud: https://arxiv.org/.
