Is investing in a Theme Fund a good idea?

I've been doing some research on Theme Funds lately, and I'm curious about what you all think. It seems like they're gaining popularity, but I'm a bit torn. On one hand, it’s exciting to focus on specific trends or sectors, like clean energy or tech innovation. But on the other hand, I worry about the risks associated with putting all my eggs in one basket. Have any of you had experience investing in Theme Funds? How did it go? Were they worth it in the long run, or did you find them too volatile? I’d love to hear your thoughts and any tips you might have!
