Can we just appreciate how labour intensive this is to make and how Nile actually came up with some great solutions even improving on the instructions he was following. Aerogel is like unobtainium, almost impossible to make. It's a material that literally can not exist without supercritial drying, yet here's a full video on Youtube showing exactly how it can be made. Amazing.

Just watched the Veritasium video on aerogel. He went to the Aerogel Technologies in Boston and when they showed the super critical drying process I noticed something that would have made your process much smoother. It appears they poured the gel into small molds and did not remove the gel from the mold until AFTER the super critical drying process was complete, doing so gave the smooth perfect appearance you were looking for.

"My favorite thing about it is that it reacts with water and turns back into silica, and it can do this in both your lungs and your eyes. The best part too, is that the particles form in the eyes under the surface, and they're way too small to remove so it can lead to permanent blindness."
Oh yeah, that's what I love about it too
