Bytes: Week in Review — Telegram’s CEO arrested, SF startups boom and Meta pivots

This week: a report from venture capital firm SignalFire seems to show that despite all its problems, San Francisco is still the place to be for tech startups in the artificial intelligence space.

But first, the arrest of Telegram CEO Pavel Durov in France has sent shock waves through the tech world. Durov is facing a number of criminal charges.

The case highlights longstanding tensions in the tech world between public safety and free speech.
