This is very disingenuous: we don't know how much spare time Sascha spent, and much of that time was likely spent learning, experimenting, and reporting issues to Slang.
It's not disingenuous, we have his and my git commit logs. I also had to deal with issues with rust-gpu. He is an expert in both the space and his project, I had never seen his project nor written any graphics shaders before. You can never get apples to apples comparisons but this is the closest I have personally experienced.
