I am pretty sure in 15 years React and Vue and Svelte will still be used frequently. Unless everything gets replaced by AI.

We're approaching the diminishing returns when it comes to front end frameworks. All the big ones are decent. I don't feel a need to have a better framework.

My bottleneck is how fast I can write logic and CSS. With complex components a lot of time is spent on managing state correctly, implementing all the minute details that the designers came up with.
