Been using flint stones for over a decade, we still don't need match sticks.

Been using a rube goldberg machine for over a decade, we still don't need a bigger rube goldberg machine.

Been using those little hand held gas lighters for over a decade, but sometimes I still need match sticks.

Same here.

Having tried TypeScript and Kotlin, TypeScript is like a half-assed type system that gives you cryptic error messages in compile time and mindfuck stack traces in run time.

Using assert(value, message?) function ends up being more useful and ergonomic.
