Others dream. Ondrej, material physicist, thinks ‘how’.
“Powder sprayed from the side, melted to substrate - laser ‘prints’ in real time.”
“People think 3D Printing is one thing. Many different things, different fields.”
A start-up prints bridges with concrete. Cool.
“3D-P is a very specific application for a specific question.”
Composite 3D-P (multi-material) would be the future…almost any object.
“What I’ve seen is, in manufacturing, it’s always about solving a specific problem - not to innovate.” Truism: today’s problems prevent tomorrow’s solutions.
Obviously, I ask about 3D-P in space.
“Velocity…powder everywhere…shielding gas - ohhh wait”
“No oxygen, no combustion; hmm might be easier.”
Nano drones could be the future of 3D-P, and biology.
“They wouldn’t follow DNA, they swarm.”
“Robot equivalent could be a line of code, maybe a blockchain.”
Is unchangeable code, akin to DNA, even possible?
“Maybe as hardware, but there’d still be software to interpret the physical DNA.”
Asimov’s laws?
“General AI could ignore it.”
Like self-aware epigenetics.
“Heard of the Boltzmann brain?”
Theoretical consciousness without hardware.
“Maybe we’re just the radio to receive consciousness.”
Maybe we’ll learn consciousness is a natural force.
You don’t create it; it's harnessed.
