I think it will be extremely useful to be able to simulate cell at real atomic level with all physics involved. That means that you can introduce changes at atomic level in DNA and see its effects. Introduce experimental medications in cell and see its effects. You can actually study cell processes (many of which are not known yet) in simulation. And many, many more. It will be revolution in medicine and in biology in general!
Any atomic level change in DNA is going to have maybe a 1-2 kcal energy difference. To properly calculate that (by running simulations) would require an economically impractical amount of computer time, and doesn't actually really change any of the hard problems in medicine.
Why am I saying this? Because I thought the same as you and it took me 20+ years to realize MD doesn't affect medicine at all.
