Ask HN: How should a 60-year-old get started with programming?

Suppose an able 60-year-old, who has never done any programming but is smart and tech-savvy as a user, wanted to get into some development work - both as a hobby/interest, but also with a look to maybe get some supplemental income from it in the coming years working remotely.

What would be a good way for them to get started? Which area could be a good fit? How could they look for remote work / monetize their hobby in the future if they find they have aptitude for it?

Perhaps one of you has had some experience in this area.
