Functional paradigm's problems are severe but people dismiss them as something we'll grow out of. If you can't tell what the code is intended to do, then the "savings" of functional are spent on more comments and documentation. Which is worse than the previous state of affairs.

It's also a little bit of Paul Graham's fault with his silly accumulator challenge. Not every language needs closures, and because closed over variables act as global variables, they might even undo the progress we've made in adopting structured programming. But by framing accumulator-capable languages as being more "powerful" now nobody wants to forgo them.
