50 years? Nope.
I spent 20 years in Semi Mfg Equipment, which supplies the machines that process wafers into chips.
For you scientists, the current tech node is 5nm. That means the smallest traces (wires) on the most dense layer of the chip, is 5 billionths of a meter.
You may wanna Google 5nm 3D NAND memory...
Anyways, using this science takes years to develop into a technology.
The technology evolves constantly; R&D is costly.
Companies (Intel, Samsung, etc) wanna get this stuff out to consumers.
Now, the government does have super scientists (and programmers!) using available technology.
At any cost...
Beyond that, companies you know develop and sell to the government under confidentiality agreements.
