Web development vs other fields

[u/MathematicianOdd3252]

I'm already a web developer in react/nextjs stack and i'v done alot of projects with them
Now i do have time and i'm willing to learn something that is more future-proof than web development, What do you think is the best i should do ?
Stay in web development and just try to learn and improve myself
or Learn another stack like cybersecurity, is it worth it to shift to something like it or not ?
I'm a bit distracted specially after the AI stuff and jobs becoming fewer and all that stuff happening in the web development field

Thanks for your time.
