You wanna store a few hundred bytes? Print some mechanical knobs and call it a day. You wanna make some real storage devices?

Hire top PhD:
Physicists for quantum effects used (and parasitics mitigated)
Chemical engineers for CVD and other very hard and expensive clean room processes.
Electrical engineers to design analog circuitry for charge pumps and multi-level cell readout technology, as well as digital VLSI/HDL design for digital logic including storage controllers
Mechanical engineers for packaging design and automation for your expensive and dangerous production line
Civil engineers for your fab plant, which is so large that significant infrastructure needs to be built to support your fab (e.g. TSMC in Taiwan funded/built a municipal scale desalination plant of which a significant fraction is used for semiconductor processes)

Until we have replicators as the other commentor pointed out, I’m afraid we aren’t even close yet. Fingers crossed we hit type II civ sometime but I won’t be holding my breath for it.
