To SHALL or not to SHALL in contracts? April 2020 VIDEO

Hello Legal Eagles,

Do you SHALL?

Ok, I know you do! :)

The question then is: how often weekly? How often daily? Per contract?

Indeed, it is truly irresistible! And highly addictive! Seems so elegant, professional, and knowledgeable, right? The client is impressed... or are they? Why do TESLA, AMAZON or GOOGLE avoid it at all cost? - The COST could be the key word here....! Of a potential dispute concerning the precise meaning of the SHALL word in the contract.So, Legal Eagles? Do you SHALL?
