You’re very sure because you’ve built one at scale? This is such peak HN. And you have plenty of other people who have never built a billing system at scale to agree with you. The OP is right, this is in fact very very hard for the reasons they say.
The idea that most people who are doing professional public speaking are reliable narrators is a bit quaint. There is a lot of room for framing that you have to allow for story telling. If you think that all story telling is about reliable narration, you're going to have a tough time being successful at it or interacting with others who are.
I ask a lot of questions on code reviews as it's usually less easily perceived as conformational and I have come to assume that I'm missing context when something is really off. Assume that coworkers are competent but may either have or lack context. If your coworkers are genuinely incompetent, then a new position might be better than fighting though PRs.
Saying this seriously a few decades after computers were room sized is I think a bit short sighted. Betting against technical progress especially in density / materials / weight is not a good bet.
That was designed as a fundamentally subversive set of lessons. I doubt we even have the will to make an accurately subversive movie version of Diamond Age (look at what happened to Altered Carbon), much less create that sort of "book".
Really exceptional response. A surprising number of people aren't aware of moral constitution, practically, even though this was a core topic for at least the last few hundred years. Interesting times we live in.
What kind of firewall work didn't have default drop? Once you take that off the table you really do have a problem but I've only seen that one in 20 years of professional work.
"Remain obsessed" with transmission of a highly contagious virus that has shown significant ability to mutate at scale? That sure seems worth being obsessed about. When it mutates to spread past all current defenses then consistently kill because we failed to stop current spread it will indeed be "depressing".
