When your bidding can be drafted and a path laid in microseconds, it's super easy to start off in the absolutely wrong direction.

On the other hand, they amplify juniors' ability to introduce errors at the same time they deprive them of necessary understanding. Having a judge rule on a bad contract idea "at runtime" is a catastrophic failure mode.
