At the same time, it seems like for biotech to have an explosion akin to the last fifty years explosion of computer technology, one would have to find a way to well and truly automate the processes involved. Last I looked, a vast amount of research is very much by hand, injecting drug into animal by hand, putting liquids in beakers by hand etc.
And part of it is living creatures are all different, and not just different in the two rocks on a beach or two toys out of a cheap mold are different. Living creatures, even two instance of the same creature, have functioning subsystems that function differently. And this is a multi-dimensional thing [1] . Custom tailored therapies attempt to take this into account but so far seem to have generally failed. I would speculate this is because humans have more than two or dimensions of difference between, even in subsystems like the immune system.
Edit: using AI to combine information on these systems that seem intractable in themselves also sounds promising - still many problem there also.
