The ability to clearly and effectively communicate, and the ability to know and recall the facts of a case is always going to be important. It'd probably be a more fair system if judges and jurors couldn't see the attorneys or even the people they're representing. Now that many cases are handled over video calls it'd be pretty easy to make that change.

A lot of communication is conveyed through more than the words themselves though and even though it's often misinterpreted people put a lot of value in that information. I suspect that even if we took away the ability to see the people involved judges and jurors would still find bias in the tone/quality of people's voices. Even if everything was reduced to text they'd find bias based on word choices, phrasing, spelling, and grammar.

Yep, just yesterday, Nike removed one leach middlemen called retailers and sell directly through their app. Turns out working out very well for them too.

The law is much more interpretation and argument based than logic routing based than you seem to believe.
