True.
>There isn't one popular technology that couldn't be *better* replaced by lisp.
False.

It is true that you can replace most/any (I didn't read all of them) of those things with Lisp, because Lisp allows you to express pretty much anything, and usually rather well.

However, the formats/syntax we see today are specialized for their specific purposes, and are equal at all and better at some of the following things:
File size for the same representation
Difficulty to humans to comprehend
Efficiency to parse/execute/use

If you can refute this, that'd be interesting to see.
