The future of computing is analog

Screenshot 2023-03-28 223058

Computer science has a long history — going back to before there even was computer science — of implementing neural networks, but for the most part these have been simulations of neural networks by digital computers, not neural networks as evolved in the wild by nature herself.

This is starting to change: from the bottom up, as the threefold drivers of drone warfare, autonomous vehicles, and cellphones push the development of neuromorphic microprocessors that implement actual neural networks, rather than simulations of neural networks, directly in silicon (and other potential substrates), and from the top down, as our largest and most successful enterprises increasingly turn to analog computation in their infiltration and control of the world.
