The X algorithm isn't "broken" or illogical.
It's an AI-powered transformer that predicts your personal probability of replying, bookmarking, or dwelling on a post based on your history & content signals.
That's why some "random" tweets crush higher-quality ones.
What's the most surprising engagement mismatch you've seen?
Drop your example ๐
mostly agree but i'd flip one part. the "dangerous" dev isnt the one who learned node in a weekend, its the one who never gets to feel the 2am outage because someone always shields them. you learn systems by owning the pager, not by gatekeeping the title. let juniors break things in staging
A backend dev who learns React in 3 months becomes dangerous.
A frontend dev who "learned Node in a weekend" usually ships the bugs the rest of us spend months cleaning up.
Most "full stack developers" are just frontend devs who can spin up an Express server.
And it's killing the quality of software being shipped.
Knowing React doesn't make you full stack.
Knowing how to write a POST route doesn't either.
Full stack means you understand what happens between the button click and the database write.
It means you know:
โ Why your N+1 query is making the page slow, not your CSS
โ When to use MySQL over MongoDB (and why "it depends" isn't an answer)
โ How a JWT actually works, not just how to copy-paste one from Stack Overflow
โ Why your Node server crashes at 2am under load
โ What a database index is doing for you, and what it's costing you
The industry created a generation of developers who can build a Todo app in 12 frameworks but can't explain what happens when you type a URL into a browser.
We glorified the stack.
We forgot the fundamentals.

Harsh? Maybe.
But I've worked across JavaScript, PHP, Java, Spring Boot, and Node long enough to know the difference between someone who writes code and someone who understands systems.
The title is cheap.
The skill isn't.
If you call yourself full stack, can you actually defend your database schema choices? Or do you just pick whatever the tutorial used?
Curious where other devs draw the line.
@elonmusk This is the kind of ambitious build that could actually make coding agents useful instead of just demo flashy. Curious how far youโre pushing the composer integration.
