I have a friend who in her 30s being a single mother of 2 kids and working as a doctor surgeon, but living in a shitty conditions in a shitty city in russia - made her way to being a well paid software engineer living in California. She started with some courses, bootcamps (one of which was created by me - this is how i know her), some first shitty jobs and gigs and gradually built herself from there. Within ~5 years. Despite some arrogant naysayers suggesting her getting a CS degree first or chose different path at all.
