For the last few years I've been using Python to build internal REST APIs and so on, and I'm also fairly well versed in PHP/Laravel. I'm not actually a SW Developer by trade, but feel I know more than enough to write/record courses for something like Udemy.
My issue is searching Udemy for any phrase such as 'Python rest', 'Python flask', 'Python web scraping' yields thousands upon thousands of results. Is it too late to start creating content for subjects like these? I'm not really a software developer, and I have more passion for monitoring (Prometheus, Grafana, Graphite, Icinga2, Statsd...) but these kind of topics don't seem worth approaching as anyone with an interest is likely already technical enough to get by, whereas learning to code has a much larger audience.
Interested to hear if I'm just being pessimistic, or whether others think the ship may have already sailed on a majority of topics.
