At the moment it would probably only work for single celled organisms but in the future its possible.
Yes, somewhere in the future. Just a few thousand years, I'm sure.
Seems like creating a new pigment would be easy it you can transcribe a protein strand from scratch.
They aren't inventing new proteins, they are duplicating existing ones.
The technology to simulate this already exists and is used to test drugs for side effects.
Oh, that explains why side effects no longer exist.
You greatly underestimate the complexity of the task here. We're talking about the permutations of every possible combination of molecules in an organism. Three molecules may be harmless when any two are taken together but may form something toxic when the three meet.
Besides, no simulation is perfect, and our understanding of physics is far from complete. I don't expect a simulation to be significantly more accurate than a wild guess, even a thousand years in the future.
Actually the formation of nerve and blood vessels is automatic, seed cells are scatted through body tissue
and use chemical signals to find and connect to similar cells.
I'll give you that. But the point still stands that the creation of gene templates for entire limbs is outright fantasy.
Because our knowledge of biology will never improve and computers will never be faster than they are now?
They certainly will improve over time. But it's still a long way to go before we can do this more efficiently than selective breeding.
PS: They currently make blue roses by watering them with dye.
PPS: Oxygen in the WATER, IN THE WATER. Like the way that BG alge already blooms in nutrient-rich outflow from rivers, drowning everything else?
