"If Ryzen is more than that, I don't see it taking a big bite out of the market. Which isn't surprising, as Intel did just halve the margins on their enthusiast parts..."
Either it is more than that, and it will take huge chunk of the market, or Intel simply reduced margins out of the goodness of their heart.
It's going to take a while, for what they have described is a process to keep extremely preterm foetus alive, rather than an artificial environment to develop an entire organism from a fertilised egg - we actually know lot about IV fertilisation and keeping it alive through the first few development stages, but there are still significant gaps to cover until you have a somewhat developed foetus that has a chance of survival outside the womb.
In parallel example, we have not managed to find an artificial replacement for egg shells which is required for avian embryos to develop. Some techniques do exist, but none of the them were able to ensure survival past the first 2 weeks. Considering that humans have been breeding chicken for centuries, there is still plenty we don't know about our favourite bird, let alone fellow humans.
