One concrete reason it might be true: proof assistants. Lean's mathlib is now big enough to make machine-checked proofs practical for research-level work, as Tao's equational theories project showed. Many contributors, a lot of them amateurs, settled ~22 million implications between magma laws in a few months. That worked because a checker verifies each contribution, so nobody has to trust the author. This changes who gets to do math. Being "first" matters less, and asking the right question matters more.
