You're my hero! This attitude is why I quit regularly contributing to this site. Any time any single person does something positive, some armchair "expert" comes out the woodworks to tell you how it won't work or can't work.
What would you prefer? Rolling applause for every idea anyone presents? One benefit of criticism is we might get to read an angle of attack we hadn't thought of and thereby improve our ideas and designs. Sure, when people blow off an idea by saying "pointless, let's save the baby dolphins first" I don't find those comments helpful, but HN almost always has far more in-depth critiques. Edit: fixed a word
Skepticism is a good thing but it's unevenly applied in the weirdest way. Solar Roadways, it seems like the smallest amount of skepticism would have dismantled the entire idea. Two nobody snake oil salesmen from out of their garage were roundly applauded by everyone to such a degree that competitors opened up.
When Musk presents a design on a much larger scale following a career of related success, it's called down?
Therefore I appreciate criticism but I'm skeptical of its sources.
