Thanks - and yeah I absolutely pre-suppose that much. I was just hoping for a more specific answer. There could be just as interesting of a story about how it went from prototype —> ubiquity. I personally don’t just wave that process off and say “meh economies of scale.” Production scaling is often quite innovative too. And many lab innovations die on the vine because they can’t cross this chasm. So the fact that this one could, after being such a holy grail for so long, is something I would love to understand more.
