Hmm. I see DNA as a template for making molecular machines,
enzymes and such, that do useful things for living organisms.
Useful things such as transforming nutrients into suitable
energy-carrying chemicals or building blocks for cell components.
Pumps to move stuff into or out of cell compartments, and many
other functions needed to make a living cell thrive.

DNA doesn't do much by itself. It's the molecular machines that
do the work.

Hmm. When I design a circuit, I don't randomly jump through
solution space. I start with something simple, then identify
limitations and add or change things to address them. I may
add bootstraps or cascodes to reduce the effect of parasitic
capacitance. Add buffers to reduce load or output impedance
effects. Add symmetry to tackle thermal or offset issues.
Change or add components to tweak phase/frequency responses.
Move components around to reduce parasitics, or to profit
from some fortuitous beneficial one. And so on.

Basically I'll choose some promising starting point and then
try to move forward through the solution space, exploring
interesting branches on the way. Rarely I'll throw everything
out and start over.

It's still a serial process. I can't see much of the space at
once. Maybe you can. So much the better for you.
