I stopped reading when I saw that this is from 2019. DeFi didn't really take off until summer of 2020

Out of curiosity did smart contracts gain new capabilities in the summer of 2020?

I believe the point is smart contracts became incontrovertibly useful in the summer of 2020.

I would love to learn why you think they are incontrovertibly useful. What are the use-cases that they are being used in?

Did it? I never heard of it.
