This seems to be written by someone who knows the surface levels of React, but not how it actually works. Which is fine, I suppose - I don't want to gatekeep someone from creating something new, but their marketing is all about being better than React. So when some (not all) of their complaints about react are somewhat fictional... it doesn't encourage me to try their work.
Neither does a week of OP doing nothing on HN but self-promotion of this work, but that is more of a pet peeve than a legit critique.
