First of all, web development isn't completed with React and Express

hype train of blockchain is already long passed and AI will pass soon too, I think you should learn what you intrests more

It means ai will go more popular in future

No, it means AI will die soon, just like crypto

don't learn what's trendy

there is still lot to learn in web dev

try different framework or play with wasm

react and next are the latest done I have completed them

go fullstack if bored in front

I have done with full stack

need for deep in programming

you can deep program in almost any "category" of software development, when I got bored I learnt rust

which became very useful for me

even in web dev

I wouldnt say ai will die soon and this isnt based on personal opinion

I have some solid knowledge of AI, and natural language processing, and have worked before with AI experts

But yes as Echo says web dev doesnt end with learning 2 frameworks

And AI is a big field to learn, just focus on one niche because i made that same mistake of learning everything

It better to learn the skills of web dev or what interest you and get a job

You can learn ai as a hobby or switch to it after if you dont like web dev but i will say AI is a huge field to learn and to land a job isnt easy compare to web dev becayse most ai jobs require degrees or masters and even without it you need tons of practical expereince through projects and need to know many things such as Statistics, data cleaning snd algorithms and deployment with kuberntes etc. Plus, lots of AI requires web dev knowledge (deployment, backend , api’s, clean code etc)
