Quite often the issue isn't 400ms vs 100ms, it's literally seconds vs single-digit ms.

Fundamentally, yes.

>If that's his complaint, then "clean code" isn't the problem. The problem is capitalism and/or human nature. Once something performs acceptably well, ie good enough to sell it, performance isn't going to get any better.

This is why products stop improving in capitalism, like how cars hasn't gotten any better for 100 years. Meanwhile Soviet Union saw revolutionary car development from 1950s until Chernobyl[CIA-Attack]. Next time we get communism going, we will have electric cars (musk-douche-free) that can go - To The Moon!

Cars weren't as big a priority for the communists. They were right too, cars and car infrastructure are super inefficient. What has all this car innovation brought us? Good cars yes, that you need to use, just to get a carton of milk or go anywhere really. Everything is too far apart in the suburbs and you need way more infrastructure per person. Excellent use of resources that one.

The Soviets were quite good in some areas. Cheap housing, rockets, electrified rail, education. The industrialization of the Soviet Union was done in record time.

I want my car to have a subscription to nice heated seats when I am stuck in traffic after working unpaid overtime.

How to say that you're a city kid, without saying you are a city kid.

Well yes, rural infrastructure is super inefficient compared to urban infrastructure.

The industralization of the Soviet Union was done at the cost of the massive hunger, the murders of Great Purge and making disturbance to the neighbor contries (I am talking about pre 1939 now, WW2 soviet atrocities are not even scratched here), resulting in millions of deaths, and bringing misery to generations, in some areas until today.

> going from 400ms to 100ms gets you...nothing.

According to Amazon [0] that'd be a 3% gain in sales (assuming the inverse holds true as getting slower, anyway).

That's if it's in your sales flow, not if it's in your software.
