I know it's very shallow but the marketing page gives me the ick. I have been Pavlov'd that websites with such designs are scams/vaporware.

Fair, but I've been following Andreas Kling since he started (publically) with SerenityOS back a couple years ago, and he's a real hacker -- as real as they come.

I've watched hours of how he works on YouTube, it's fantastic, if anyone can lead a browser team, its him.
