Matt Ahlborg, founder of PPQ.ai, rejoins the show for an update on the rapidly evolving AI landscape. PayPerQ is a bitcoin enabled ai platform that enables users to easily use all of the top ai tools without an account. Users pay per use with bitcoin and can switch the models they use on the fly without needing to provide an email address, phone number, or billing address. We discuss the rise of lean teams supercharged by AI tools, the subscription vs. pay-per-token model debate, and why massive subsidies from companies like Anthropic and OpenAI likely will not last. Ahlborg breaks down PPQ's "AutoClaw" smart routing feature that blends cheap and expensive models to cut costs, the addition of secure enclave models for privacy conscious users, and how OpenClaw's explosion drove a 400% revenue increase for PPQ.

Evgeny is the founder of SimpleX Chat, a private and secure comms protocol that has a radically different approach to the concept of user identity. We discuss how SimpleX's unique transport network assigns addresses to connections instead of endpoints, why MLS is flawed, the upcoming scalable channels feature to compete with Telegram, and how the network plans to sustain itself through a model where large channels fund infrastructure.

We cover SideSwap's atomic swap markets, their peg-in/peg-out service, and how partners like Aqua Wallet are plugging into their infrastructure.
