It seems like the "language wars" are mostly over & now we're in the "LLM wars" era. However, if you still enjoy programming choice of programming language still matters.

Ruby is still amazing, even if it's not the fastest, even if it doesn't have the most tooling or libraries.

Don't be fooled, LLMs don't think, they don't reason, they just perform calculations to find out which is the most likely next word. They make stuff up all the time.

Stop idolizing them & never stop learning. https://t.co/aD37zJ1ePz

Vibecode all you want but what's the point if you never understand what you're really doing? How are you going to avoid security issues & fix the real issues when the LLM fails you?

Even in this AI era it's crucial to keep learning. Check out my blog: https://t.co/aD37zJ1ePz
