Instead, I feel it's enabled us to more freely choose what frontend framework(s) we want to implement. Based on the problem we're trying to solve.
There's only so much that 1 human can become an expert at. Before AI assistants, we had to make some choices: I cannot become an expert at React, Vue, Angular, Svelte, SolidJS, Quik, and Astro/Alpine/HTMX simultaneously. Too much. So I must pick one or two that I think are best-suited for me. Learn them deeply. Then apply them everywhere.
With AI assistants, there's more freedom. I'm not an expert at Svelte. But if there's a web problem I feel Svelte would solve best? Then that's what I can use. If I really need React's virtual DOM? Then go that direction. If what I'm building is so simple that a static website with basic HTML and JS and a CSS framework is sufficient? I can go that direction.
Granted, there are absolutely risks for relying on AI assistants to write code you don't comprehend or understand. There are times I'm okay with it. And times I am not.
But as for your question, am I less-likely to use frontend frameworks now? No, I'm actually using them more than I did previously. I'm just being choosier about what I truly need, versus what's overkill.
