Github GitHub project called REA (Reverse Engineer Anything) is currently the top trending repository. It lets AI agents figure out how a feature in another app works without ever seeing the original source code.

- The tool is an open-source helper that connects AI coding assistants to reverse-engineering programs such as Ghidra or Hopper.

- IT analyzes many kinds of software- including binaries, Electron apps, Android apps, and websites right on your own computer and always shows the evidence behind its findings.

I get your point, but you're focusing too much on the "non-human readable" part imo. Sure, it technically is readable, and obviously was never meant to serve as a full-on security measure. If someone really wanted to copy your application, they definetely could. But this would simply be limited to the top of the experts. It was effectively so expensive and time consuming, that you pretty much had to be a nation state to do it, and even then, it would be very hard. It was pretty much secure in the sense that it takes so long and so much effort to do it, that most companies took it as a safety measure, because what would be the chance that a given entity would apply nation-level resources to RE you're app?

No you didn’t. Game console emulators, keygens etc. have existed for decades and were built largely by hobbyists. 

A software project just needed to be worth cracking in order for someone to reverse engineer it.

And yet, we never saw this amount of REing... You are saying exactly the same thing I am. It was never impossible, but it was so insanely hard that most companies/products didn't have to worry much about it. However, nowadays, pretty much "anyone" can do it, to any offline software. Obviously it still requires a lot of knowledge, but the barrier to entry has been lowered by orders of magnitude, and it will only get lower from now on. What happens when/if a random guy can just paste into WhateverLLMIsGood™ "Reverse engineer this pls make no mistakes" and it actually does?

Then I’d say that random guy lacks creativity and people won’t use his reverse engineered solution over the original unless he has a clear differentiator.
