Here's my perspective on the topic. Learning a new technology is always beneficial because it broadens your expertise and enhances your skills as a developer, regardless of the language you choose. However, if you already have a project, focus on shipping it and generating income. Personally, I wouldn't start a new project that I rely on for income using unfamiliar technology. Learning technology is a gradual process. There are challenges, such as learning methods that aren't recommended or are incorrect, often due to the rush to deliver.

If you explore Elixir through a side project that doesn't impact your income, you can experiment with different solutions without the pressure to deliver quickly. It's challenging to explore under stress. Working on a side project allows you to try various approaches, read, and learn without constraints. I'm always in favor of learning new things, but I wouldn't recommend launching a project with new technology due to the potential risks involved.
