The great things about analogic
- Modules with well known input/output relationship
- Well known composition functions
- "just plumbing signals between these"
- Easy to debug, the "real" signal can always be probed

Why not do everything like that ?
The problems with Analogic
- Noise
- Lot of specific components
- Complex supply chain
- Expensive ($$)
- Really slow design cycles ($$)

What if this was a reusable component we could adapt on the fly

The advantages of Digital
- Fixed noise (only ADC and DAC)
- Infinite transformation complexity
- Fast and cheap design cycles, just recompile
- Reusable components with near infinite reuse
- We still use 30 years old design today in new products
