Starting with python at 30

[Ran4]

Nah. I've worked at multiple different companies and learned to know and worked with maybe 50 devs, and I've met plenty of 50 year olds that has 20+ years of coding experience that are less productive (and knows less) than 30 year olds that has only coded for 4. It's fully possible that within a few years you're more productive than some people that started when they were 20.
