Hesitation

Hesitating to act because the whole vision might not be achieved, or because others do not yet share it, is an attitude that only hinders progress.

- Mahatma Gandhi

Analog vs Digital

Analog systems always exhibit graceful degradation.
Implementing graceful degradation in digital systems is HARD.
A single part failure in a digital system may lead to a catastrophic failure. Thats the nature of binary logic. A single inversion of value can lead to complete failure of system.
