This is a pretty shitty, non-constructive response. I think neural differential equations are not easy to wrap one's head around even if you have a solid understand of deep learning and differential equations.

Sure, if they spent a lot of time wading through the literature they'd probably understand fine, but the point they were making was that the post was quite unapproachable without having delved into the specific literature on neural differential equations.

I think this is a reasonably valid complaint, and does not warrant you implying that they don't deserve their job.
