I did some research regarding Smart Contracts and I can say I did not conclude to anything specific.
Do you really believe that Smart Contracts can replace a lawyer?
And has anyone actually tried to have any kind of exchange and used one Smart contract?
Thanks, everyone in advance who will answer! I would love to hear some opinions.

I think smart contract doesn't mean it is smart enough to become your lawyer.
Same as your smartphone, it cannot become something like lawyer just because it is smart.
Smart means they can compute or automate anything with their knowledge base in their system.
