It’s Reddit….not an actual NASA board meeting. People don’t need permission to just throw out random thoughts. This doesnt lead to anything.

> The starting assumption is that people are being stupid […] which comes about from this bias toward personal superiority and intelligence

I’m kind of getting some projection vibes from this comment. You complain that someone would have the balls to have a random thought about how to clean the dust because they’re assuming people from different space agencies are stupid but then also say “well they’re not smart enough to think of a solution like this”.

You seem to be taking this all very seriously. I’m not sure who you are or what you do. But Reddit isn’t where NASA or ESA or SpaceX or whoever comes to for solutions. There’s literally no harm in anyone writing anything here as a fleeting thought. And to go ahead and write 4 paragraphs about why someone should feel bad about making a comment on a discussion forum is pretty silly.
