The paper "Is this the simplest (and most surprising) sorting algorithm ever?" introduces the "Sleep Sort" algorithm, a conceptually simple, albeit impractical, sorting method. It relies on spawning a separate thread for each element to be sorted. Each thread sleeps for a duration proportional to the element's value and then outputs the element. Thus, smaller elements are outputted first, resulting in a sorted sequence. While intriguing in its simplicity, Sleep Sort's correctness depends on precise timing and suffers from significant limitations, including poor performance for large datasets, inability to handle negative or duplicate values directly, and reliance on system-specific thread scheduling. Its main contribution is as a thought-provoking curiosity rather than a practical sorting algorithm.

A few users note its potential educational value for understanding sorting network concepts.
Paul Graham argues that the primary way people get rich now is by creating wealth, specifically through starting or joining early-stage startups. This contrasts with older models of wealth acquisition like inheritance or rent-seeking. Building a successful company, particularly in technology, allows founders and early employees to own equity that appreciates significantly as the company grows. This wealth creation is driven by building things people want, leveraging technology for scale, and operating within a relatively open market where new companies can compete with established ones. This model is distinct from merely getting a high-paying job, which provides a good income but rarely leads to substantial wealth creation in the same way equity ownership can.
Hacker News users discussed Paul Graham's essay on contemporary wealth creation, largely agreeing with his premise that starting a startup is the most likely path to significant riches.
