This is an awesome technology. There is vast good it can do in medicine, biotech, materials science, etc.
But how concerned should we be with novel proteins being pumped into the biosphere? What does each new design do to our immune systems and ecosystems? How robust are these systems to, in effect, any protein that can be printed, and any substance that they can catalyze?
I am skeptical that a regulatory regime could reliably predict the consequences of releasing novel proteins via simulations or small scale experiments.
