Every single time I see someone 100% sure that something is gonna happen I become 100% sure it will never happen. and if it does happen then it's definitely NOT what we have expected.This is kind of like saying "let's wait until the new Lamborghini comes out before we worry about the cost"
It is pretty unlikely that it won't come out, to be honest; that's not something that can be said about most of this sh*t. There is literally no other company in the world working on a hairloss solution with the kind of power these three have and so far, they've remained on schedule with no setbacks. If it doesn't come out in 2020 (which is not even two years away now), I doubt it will be long after.
So people worrying about the feasibility of them actually getting the treatment for themselves is perfectly reasonable.
And as has been discussed, in this thread twice, experiments in the late 90s did this kind of thing in a human via human cells from two different people as well and it worked.
That's a fact that everyone who doubts this thing is going to work conveniently ignore.
