I'm pretty sure the merits of typed vs untyped has been going on since the 1950s at least. 30 years is such a specific period of time that it makes me wonder what happened in the early 90s that the author is referring to.

And JavaScript and Python, and a whole host of languages that didn't care about strong typing

None of these were the first untyped languages, or even the first widely used untyped languages.

Ruby and Python are both strongly typed. They are not statically typed.

In fact none of them are "untyped". They are strongly typed.

BCPL could conceivably be described as untyped.
