I’m currently learning it. I like the concept, and no other conlang/auxlang has become as widely spoken or treated as seriously as Esperanto. There are actually children who are native speakers, as in Esperanto is their first language, no other conlang can claim that.

However, as many users here have pointed out, it has problems. It’s very Euro-centric. So while it is easy for romance language speakers to pick up, if you are from a different language family, it’s no picnic.

There is also the issue of relevance. Esperanto has a fairly active online community, you can pretty easily find Discord servers and forums with several hundred to 1000+ active speakers from all over the world.

If you are lucky, there are local clubs and groups that meet up in person and speak Esperanto to each other.

Esperanto has also been shown, at least in children, to aid in learning a second language. Learning Esperanto helps you get used to the process of learning a language in general, and basically gives it to you in easy mode.

But if your goal to learn a second language is utility, then Esperanto almost certainly isn’t a good choice. For instance, I live in the US, and not in a region that has a high Hispanic population. That being said, I still encounter 3-5 people a month who are Spanish speakers. So even for me, learning to speak conversational Spanish would be much more useful as a second language than Esperanto.

That’s actually my long term plan, to start with Esperanto because I really struggle with learning languages, even Spanish has been too tough for me. But Esperanto has made it easier so far, and it’s fun.

Ultimately, Esperanto would have been a far better world language than English, which annoyingly has become the de-facto world language, and I say that as a native English speaker.

I don’t see anything like Esperanto arising anytime soon, if ever. If you think it’s cool, learn it, you’ll at least learn how to learn a foreign language better and you’ll maybe find some new friends online, can’t complain about that.
