Writing an OS kernel is fun, but very few OSes have wide adoption. That's not a reasonable goal to have, unless you've got a large customer lined up where your OS fills a need for their product intended for wide distribution. If you want to build an OS, build it for fun, build it because you're bored, build it to learn, maybe even build it to show your language is capable of doing it. But don't build it with the expectation that it will get a large amount of use. Especially if your OS is intended to be general purpose. If you wanted to build an OS for embedded stuff, you might find a niche, resource constraints mean there's more room for variation and making tradeoffs.
