In the next 5 years, humans will spend lots of time convincing themselves and others that they're better at tasks than AI, or using regulation and laws to prevent AI from performing tasks, even in circumstances where AI is obviously and objectively better.

Unpopular opinions 1. Yield focused defi does not adequately compensate users for the risk involved. 2. Only stablecoins and on chain stocks have real, sustainable product market fit. 3. At most, we need 4 or 5 decentralized layer 1s. 4. Decentralized layer 2s are generally not decentralized and are increasingly pointless while adding significant complexity, splitting up liquidity and negatively impacting the user experience. 5. Microstrategy is a net negative and we would be better off if Saylor had never entered the space.

Digital assets are entering a new phase. What once ran in parallel to existing financial systems is increasingly being applied to solve practical, real-world needs — often behind the scenes – from cross-border remittances to B2B money transfers. This creates new opportunities to add value in how money moves globally. Today, we introduced the Mastercard Crypto Partner Program — a global initiative that brings together more than 85 crypto-native companies, payments providers, and financial institutions. Together, we're creating a forum for meaningful dialogue and collaboration as this space continues to mature.

this is one of the clearest explanations of why prediction markets matter that I’ve seen. Vitalik is basically saying: > prediction markets aren’t about gambling, they’re about forcing accountability into beliefs. > on social media, people get rewarded for being loud, extreme, and wrong. whereas on prediction markets, you get punished for being wrong and that flips incentives completely. > what’s powerful here is the idea that markets discipline narratives. you can scream "this will definitely happen" on X and get likes, but the moment you have to put money behind it, uncertainty suddenly matters. that’s why prediction markets feel healthier than most info ecosystems: > lies are costly > confidence has a price > reality settles arguments they don’t eliminate misinformation, but they price and that alone makes them one of the most honest coordination tools we’ve ever built.

You are entering the final stages of undevelopment. The brain drain to dynamic economies will soon leave no technical workers on your shores. Tourism will soon be the largest contributor to your economic output. Your entire workforce will soon be educated in manufactured disciplines like social business studies—and their only skill will be regulatory lawfare. Your descendants will look back and wonder how you squandered the opportunity that Europe had.
We Europeans have our laws. You will have to learn to acccept them
