Episode notes

Alex Blania (CEO of Tools for Humanity, Co-Founder of World, and Co-Founder of Merge Labs) joins Sourcery to explain why the internet is heading toward a breaking point: bots, deepfakes, scams, and autonomous agents are scaling faster than trust.

“99.9% of internet traffic will be AI driven.”

“It’s not about combating the bots because that will be a lost cause.”

World is trying to build a “real human network” a proof-of-human layer for the AI era, and the numbers are getting serious:

• 38,374,194 World App users across 160 countries

• 17,832,402 verified unique humans

• 970,885,726 wallet transactions

We talk about: how proof-of-human actually works, what happens when bots outnumber people online, why identity becomes the bottleneck for markets and platforms, and what a “verified human internet” could look like.

Then we go deeper into Alex’s second frontier bet: Merge Labs, a brain–computer interface research lab that raised $252M seed round at an $850M valuation, backed by Bain Capital Ventures, with OpenAI as an investor and research collaborator, plus Gabe Newell. Merge Labs is pursuing less-invasive, higher-bandwidth BCIs, exploring ultrasound-based modalities and molecular approaches to interface with more of the brain without implants.

The bot era is here. The question is: how do you prove you’re human online, and what happens when you can’t?
