<p>Here's an analogy that might make it clearer:<p>Alice is in a wheelchair.<p>Bob has a broken leg.<p>Charlie is unfit, but otherwise a healthy adult.<p>Alice, Bob, and Charlie would all say "I find getting up the hills of San Francisco difficult". But "doesn't everyone find that hard" conflates the causes and severity of the difficulty for the three of them in a way that isn't useful for making their complaints feel heard, or addressing the complaints such that they don't have that issue.<p>For example:<p>Alice could get an electric wheelchair.<p>Bob could take public transit / Ubers up, or get rides from their friends.<p>Charlie could take up running with friends.</p>

<p>The question on my mind: how do you figure out what the functions do without reverse engineering?<p>If I were to guess, you're saying that you reverse engineer the API boundary without reverse engineering the implementation. But then figuring out what the API contact is without documentation seems intractable for most API boundaries.</p>

<p>> I should be able to state that two species have a different lifespan based on a difference in mean age of death - without needing to provide any specific biological mechanism in my study.<p>You need to control for confounders. For example, if I told you:<p>- Mean lifespan of species 1 is: 3 years
- Mean lifespan of species 2 is: 10 years<p>Does that mean that species 2 has a longer lifespan than species 1?<p>What happens when you find out that species 1 is domesticated cattle, which has (almost) all of its males slaughtered at age 2?<p>You could then say "I meant for two species that are in controlled conditions", but now you need to define what conditions you're controlling, which implies what casual mechanisms you're controlling for.</p>

<p>> How does someone find his game before really really good games like baldur gates etc.?<p>They don't. There have been really good AAA games before Jeff started making games. His business model does not revolve around getting people to play his games before they discover better ones. His business model is to make games that can't be compared like that.</p>

<p>> You're paid what you're known to be worth.<p>You're paid somewhere between the minimum amount you'll accept and the maximum that the company is willing to give you (which in the case of some VC funded companies, may exceed the amount of profit you generate!)<p>Where you're paid on that spectrum depends on how much leverage you have vs. the company.</p>
