Is it nobody knows how to make the jump from basic physics to predicting cell behaviour (sorta like quantum/classical), or would predicting the behaviour just require too much compute power?
That's what everyone tries to do but it's fatally flawed, especially since the practitioners are often clueless about some of the soft emergent behaviours in between (like chemistry). As Sydney Brenner quipped, modern systems biology is low input, high throughput, no output science., Or as a cs person might say, GIGO principle in action.
