But mental discipline required to write efficient and scalable code is insane that most domain expertise is feeble by comparison.

Efficiency is about using minimum cpu cycles or minimum memory or minimum network round trip or more generically using minimum/optimum resources to get something done.

Scalability is about minimizing bottlenecks and linear scaling so one can just copy and execute by adding more nodes/resources and expect correctness and increased throughput.

Both of these have nothing to do with domain expertise.

Domain expertise is hard but not that hard compared to the insane mental discipline required to write efficient scalable code.

Domain expertise is valuable and hard but I don't get this "domain expertise is harder than disciplined coding" mentality.

This has always been true since the dawn of programming.

Chaining unrelated sentences is retarded. Chaining sentences like most people is common sense. Chaining sentences airtight is math.

You ask what a true mathematician does. He chains sentences like everyone else but with an effort to make them airtight.

Buddy. That is not how winning looks like.

If casualty count is your criteria, then Soviet Union was defeated in world war 2 according to you.

If you think distributed architecture is about rescuing a bunch of people, then clearly you haven't done any serious work in your life. Go write some code and build some distributed systems.

Really?. Funny that everyone now knows US overclaimed their capabilities.

Iran alone is beating the shit out of US. Thinking it can steamroll Russia is not even funny. Some serious epidemic of Hollywood syndrome permeates the US.

And what has it to do with distributed architectures. You must not be good at what you do.
