It's not the same context really. A lot of languages have lambdas, and had before Java such as js, python.. but in these languages, it was an obscure feature.

In lisp/fp it was the "only" feature. People were thinking in how to encode anything with lambdas and not with the usual imperative traits (prog, do, loop). Consider that in 75, the first scheme paper was already talking about CPS (aka pre-monadic style).

I'm not making value judgement, it's just that using parameterized code blocks in LINQ select/where or java streams or python map/reduce is just the very first step in a long series of stairs. And monads are on the 3rd floor kinda.

So to the fp crowd it's business as usual, but for the rest of the world it's a twisted idiom at first.
