Great work by everyone involved. SerenityOS is for me by far the most interesting project in tech right now. It's like watching a different branch of reality evolving. The recent browser optimization videos by Andreas himself have been great. A great moment in particular was seeing Andreas' satisfaction when he go smooth hover effects on links[0], a single moment where he is (presumably) struck with how far his project has come.
