Magical Systems Thinking

news.ycombinator.com Ed Bradon 2025-10-03 01:18:27

The systems that enable modern life share a common origin. The water supply, the internet, the international supply chains bringing us cheap goods: each began life as a simple, working system. The first electric grid was no more than a handful of electric lamps hooked up to a water wheel in Godalming, England, in 1881. It then took successive decades of tinkering and iteration by thousands of very smart people to scale these systems to the advanced state we enjoy today. At no point did a single

Donald Trump, who was backed by a bunch of tech billionaires during this past presidential election, is busy transforming America into a corporate dystopia straight out of the 1980s science fiction films that those billionaires have long admired for all the wrong reasons. For one thing, Trump has fully embraced AI—helping to cut what little regulation existed under the Biden administration, in an effort to further liberate the already blossoming and disruptive new industry.

How Often Should You Replace Your Mattress and Bedding?
