1. 1

   Why does Pavel Durov avoid using a phone?

   Pavel Durov avoids phones because he wants to set his own agenda before anyone else can set it for him. He says a phone is not a necessary device and recalls growing up and going through university without one. When he later had a mobile phone, he kept it on airplane mode or mute because he hated being disturbed. His larger point is about attention: he wants to decide what matters in his life instead of letting people, companies, organizations, social media, or news tell him what to think about. He connects this to quiet mornings, when he lies in bed thinking, showers, and exercises without a phone. Opening a phone first thing in the morning, in his view, turns a person into someone told what to think about for the rest of the day.

   What happened to Pavel Durov in France?

   Pavel Durov says he arrived in France in August for a short two-day trip and was met by about a dozen armed policemen. They asked him to follow them, then read him a list of roughly 15 serious crimes. He says he first assumed there had been a mistake, then realized authorities were accusing him of crimes that some Telegram users had allegedly committed and treating him as responsible for them. He was put in a police car and held in police custody in a small room with no windows and a narrow concrete bed for almost four days. During questioning, police asked how Telegram operates. Durov says he was struck by what he viewed as a limited understanding of technology, encryption, and social media by the people behind the investigation.

   How does Telegram run with such a small engineering team?

   Telegram stays small by treating headcount as a liability unless it directly improves the product. Durov says the core engineering team is about 40 people, including backend, frontend, designers, and system administrators. His philosophy is that more employees do not automatically create better work. With too many people, coordination consumes time, underused employees demotivate others, and people may invent internal problems instead of building. He also says refusing to solve every workload problem by hiring forces automation. Telegram runs tens of thousands of servers, almost 100,000, across continents and data centers. Managing that manually would require thousands of people, so the team builds algorithms to operate the infrastructure. Durov says this makes Telegram more scalable, efficient, reliable, and resilient when parts of the network go down.

   How does Telegram's end-to-end encryption work?

   Telegram uses a hybrid encryption model because Durov says different chats need different trade-offs. He says Telegram was already designed to be secure in 2013, but the Snowden revelations made the privacy problem clear and pushed the team to add secret chats where not even Telegram can access messages. Secret chats are end-to-end encrypted, cannot be screenshotted or forwarded, and are intended for people who do not even want to trust Telegram. Durov says that same design becomes limiting for large communities, persistent chat histories, huge channels, bots, document sharing, and multi-device use. For those cases, Telegram relies on encrypted cloud chats. He also points to open-source apps and reproducible builds for Android and iOS, saying they let users verify that the app downloaded from an app store matches the code available on GitHub.

   What was Pavel Durov's poisoning story?

   Pavel Durov describes a 2018 health crisis that he believed might have killed him. He says it happened in spring 2018 while Telegram was raising funds for TON and facing attempted bans in multiple countries, so he did not discuss it publicly because he did not want people or his team to worry. After coming home to a rented townhouse, he noticed a weird neighbor had left something near his door. About an hour later, while alone in bed, he felt acute pain throughout his body and says his eyesight, hearing, breathing, and other bodily functions began to fail. He thought, "this is it." The next day he woke up on the floor, extremely weak, with broken blood vessels across his body. He says he could not walk for two weeks and felt more free afterward, as if living on bonus time.
