I started in tech at IBM supporting the finance clients. When I moved to an ISP in the early 90s I was dumb struck by the fact that things broke and it was okay. Oh the Usenet server failed again....etc...it never sat well with me. Look SNA was complex, but uptime on the system I support was measured in decades. I have done a ton of startups since then and while I love the speed at which we move the falgility of the system always rubbed me wrong. Looking at the need for speed (mongo, et.al) was always painful. I am happy to see that rational thought is winning (which is how I see this).
