I don't think the author completely feels this way. He feels Typescript is the VHS to his Betamax: the approach that won out despite being technically inferior.

> unfortunately, I see that nowadays, TypeScript won. The idea of strict type-checking for JavaScript is less popular than in 2019.

> [Typescript's types] give people a fantastic tool to cover existed code with types but doesn’t force to re-design it to make it safer.

By 2019, typescript was for some time dominant over flow and had won the js ecosystem, so either the author was naive to this or isn't quite portraying the story well.. I think it should be fine for the author to say they had personal preference over something like flow and so you developed tools to their own preference

Yeah in 2019 Typescript was already the clear winner, no contest
