Some devs are leaning a bit too hard on AI for solutions and workflow.
In my latest video I show a few examples and give some advice on what to do / use instead.

Looking for more examples of dumb uses of AI. Let me know if you've come across any.

Looking for more examples of dumb uses of AI. Let me know if you've come across any.
What dumb uses of AI have you come across?
I'm thinking of things that have existing deterministic solutions, vs expecting an LLM to get it right every time.
Examples:
"Given this email extract all phone numbers" vs regular expressions
"Convert JSON into a type" vs IDE extension

My talk from UtahJS on @vuejs.org ejs.org Vapor mode is up!
I start the talk with a quick history of rendering strategies in frontend JS from the past 15 years and then show what Vue vapor mode is and how to try it out.
The future is fast 😎

I've been collecting thoughts about this for a while now. Finally took the time to put it all into words. You might not agree. That's okay. I'm just starting the discussion.

In my latest video I talk about what classless CSS is, why you might use it and showcase a few of my favorite frameworks.
I also share a tool I made to compare 69 classless CSS frameworks side-by-side.
