Ask HN: Hobby programming language, waste of time?

I've been working on a functional language for a couple years now in my spare time. I generally enjoy, although I'm aware that I'm not exactly creating any assets that would have monetary value in the future. I sometimes question if there is a point to this. One thing I know is that it's not 1990 where people are writing web applications in C. We have many dynamic memory safe languages like Python, PHP, Ruby, JavaScript, etc, so there is no need for yet another dynamically typed language.
