> Similar to how building houses is pretty straightforward. Because we've been doing it for decades. The railroad wasn't straightforward to build when it first started. After a century there sure are lessons learnt. The conventional apartment building, or the conventional sky scraper, are not in the same league as some mega construction projects out there, so it's not always "straightforward". Even though most startups and enterprises are solving very similar basic problems, the field itself is still quite young and open to innovation. In a century, perhaps building fairly complex social network with fairly high traffic might be as straightforward as setting up a Medium account, but we're not there. Like you said, there are many issues that are not easy problems to solve yet: dev ops, CI, etc.
