work with steve jobs, or someone like him.

> One of the best, if possibly exaggerated, examples of the reality distortion field comes from Jobs's biographer Isaacson. During development of the Macintosh computer in 1984, Jobs asked Larry Kenyon, an engineer, to reduce the Mac boot time by 10 seconds. When Kenyon replied that it was not possible to reduce the time, Jobs asked him, "If it would save a person's life, could you find a way to shave 10 seconds off the boot time?" Kenyon said that he could. Jobs went to a white board and pointed out that if 5 million people wasted an additional 10 seconds booting the computer, the sum time of all users would be equivalent to 100 human lifetimes every year. A few weeks later Kenyon returned with rewritten code that booted 28 seconds faster than before.

This feels like a bad ancedote

A) kind of sounds like a toxic work environment

B) this is a bad way to reason about performance without knowing more. Is this actually a bottleneck? Would the heroic effort be better spent saving minutes elsewhere where its easy to save time instead of saving seconds during boot where its hard to save time and users encounter relatively rarely? Optimizing boot might be the right call but it also might not be.

Anything can be optimized. The real trick is to optimize your optimization so you optimize the right thing to get the most improvement possible as you are almost always limited by the amount of time you can spend optimizing so you can't do it all. Picking a component at random is a terrible way of doing optimization.

Didn’t use an original Macintosh, but I used a Mac Plus. It was pretty typical to turn your computer off between uses. This optimization was very valuable.

I don't think anyone's ever argued that Jobs was toxic af to work with, however some engineers respond to that kind of treatment by producing best-in-class work. It's one of those trolley problem style questions, would you want this software to be twice as good at the expense of knowing ten devs were bullied like that?

Clever. Imagine how many lives are wasted by online ads with this reasoning...

Kinda sounds like gpt prompting
