"Imagine if someone were to suggest that all web infrastructure should share the same database. That would rightly be seen as an absurd idea — but that’s what Web3 advocates are essentially suggesting. A blockchain is a distributed append-only database, spread across multiple nodes, but it is still one single database. In the name of decentralisation, Web3 advocates in fact seek to create a new form of centralisation around the blockchain."
> Cryptocurrency is one of the worst inventions of the 21st century. I am ashamed to share an industry with this exploitative grift. It has failed to be a useful currency, invented a new class of internet abuse, further enriched the rich, wasted staggering amounts of electricity, hastened climate change, ruined hundreds of otherwise promising projects, provided a climate for hundreds of scams to flourish, created shortages and price hikes for consumer hardware, and injected perverse incentives into technology everywhere.
