You're ignoring that we're pushing these languages a LOT more today than we did back then, it doesn't even compare.
I also wouldn't call their feedback loops "fast"; you lose all state between reloads, you're switching application focus back and forth, and more.
It's easy to get angry about losing your pet features without realizing Lisp had it much, much better all along :)
For example the ClojureScript SPA I'm working on has been running for the past day and I've done countless iterations on it, as it runs without ever rebooting it. It receives data from a few websockets and displays it live; I can be the user AND the developer at once.
Iteration times are almost instant without changing application focus; that's easily a few times faster than the feedback loop you mention! Not even counting the fact that you get a live REPL into the running application. And setting all that up was easier than following a LAMP tutorial.
