This doesn't really repudiate anything you say in the essay. But people shouldn't get the idea that just because there is resistance, they are doing something good. There needs to be a reason why the critics fail to see the light for you to claim you're working on an overlooked problem.
The trick here is that while you're working on it, you don't know if it something that needs to be solved.
