Capital Cycles and AI

Mule’s Musings • 629 implied HN points • 13 Jan 25
💼 Business Technological Innovation
  1. Everything goes in cycles, including money. When investors see high returns, they jump in, but eventually, too much investment leads to lower returns.
  2. The current boom in AI feels different because it lacks a strong feedback loop that typically drives rapid investment increases. We're not yet seeing the big jumps in value that signal a bubble.
  3. Power and data centers are crucial for AI's growth, but they have slow response times. This means there might be overbuilding, which could lead to shortages and demand outstripping supply in the future.

  2. The success of Bitcoin depends on trust in its underlying technology, how widely it's accepted for transactions, and how securely it can be stored. Without strong trust and use, its value might not hold in the long run.
  3. For Bitcoin to thrive, it needs to be used more broadly beyond just enthusiasts. If people can trust the system and find it convenient, it could evolve as a currency despite its current limitations.

AI Petrocurrency: The Imminent New Reserve Currency Mechanism

Nano Thoughts • 0 implied HN points • 01 Jul 25
🇺🇸 U.S. Politics Technological Innovation
  1. The 'petrodollar' system was created when Saudi Arabia agreed to sell oil only in dollars, which made the dollar crucial for global trade. This created a consistent demand for the US dollar and solid economic power for the United States.
  2. AI could follow a similar path to the petrodollar by becoming essential for decision-making and automation across economies. Countries may rely on a few nations, like the US and China, for powerful AI technology, creating new dependencies.
  3. If a country wants to integrate AI into its systems, it will face high costs if they ever try to switch away from that AI provider. This could give the AI-exporting country significant leverage over the importing nations.
