Contract signing – painful, expensive, ugly

The issue of contracting digitally has been solved. There are thousands of ways to sign a contract. However, a couple of things concern me that remain unresolved. The main contract management systems were founded 15 years ago and look terrible. Speed, aesthetics, and cost are lacking. I don't want to spend a lot of money and time and suffer from bloodshot eyes just by signing an NDA or SAFE. It should be fast, modern, and inexpensive. What do you think?
