Funniest part of that video for me is the disconnect between the science (Alexie) and the business itself. He openly says that they have a long way to go before this might be available (3-4 years and probably longer in his own words as of late 2020), yet in the business calls with the VC backers they sound like they are racing forward towards clinical trials and quick commercialization.
The biggest take away from it though is that he states that the challenges they still face are not fundamental, but rather small and technical. I think most people will be able to wait 3-4 years for a perfect hair of hair, though.
