Ya got an idea, you make a prototype. Got it done in two days. You made it happen with Wordpress.
Your idea caught on, you need to add features. You added code, everything breaks.
You kept coding, it worked for a while.
Then your app ran out of memory. You tweak and optimize, but PHP don't provide garbage collection.
You wish your app can talk directly with the OS. You wish you made your prototype with Rust instead.
Your app is now out of control.
