When the internet was becoming a world-changing technology, there weren't thirty years of websites to keep working and malware to protect from, web standards were far simpler, and a much higher proportion of users were enthusiasts who were excited by anything they could get and didn't mind if things were rough around the edges. Similarly, two brothers could make the world's first aircraft that flew under its own power, and yet with the combined might of everyone working for Boeing, people are worried about airliner doors falling off and an eight-day space trip has become an eight-month one. Mature technologies need a lot more effort to build and maintain than emerging ones.

But it does mean you can spend forty hours a week or thereabouts putting effort into a particular goal and maintaining the knowledge, skills and experience to keep doing it to a high standard without having to sink time and effort into something else in order to get paid enough to live on.
