Can any one explain what they mean by simulate? Like to what depth? Do they define different types of cells and their functions and then let them work? Or molecules, atoms? particles?? I strongly believe a "proper" simulation is impossible because we don't even know the bottom of the barrel, so best we can do is define a building block and how it behaves and see it grow from there. Although the coolest thing would be to define the quarks and four forces and then let it organically grow into some kind of matter over time. We can also control time in a simulation which will basically confirm our understanding if the outcome of the simulation is similar to real world.
