You're right, I can learn the basics of regex in 30 minutes. Then I can write my one regex. Then I can forget the basics of regex in 3 minutes, because regex's syntax is random garbage that makes no intuitive sense, and I hate and suck at memorizing nonsense. Repeat every 4-16 months.

It's true though that regex is entrenched enough that even if something is easier to read, it's unlikely that it'll replace regex any time soon. You'd need a couple big names to adopt it, then many years.

But if there's a readable replacement that can convert to and from regex - well, screw it, I'm in. Even if I'm required to use regex in some program, if I can write something that makes sense without the requisite half hour of googling crap, I'll just use it as a separate tool to make and read regex strings.
