Platforms are competitions and, today, the web is losing. Yes, mobile OS duopolists have suppressed the web, but that's not the only reason users spend an increasing fraction of their time in native apps.
Over the past decade, frontend failed to mark its priors and practices to market, making sites harder to use for many. For the web to win, we have to snap out of it and make clear-headed choices about what really works.

Paul co-founded the Engineering Department within Bloomberg’s London office, which has now grown to 1,600 developers. He built the previous UI stack for the Bloomberg Terminal, and has been very closely involved in the transformation to embedding Chromium for the entire UI and application execution engine.
Over the years, the Bloomberg Terminal has evolved from one of the first computer-based desktop products running on custom hardware, through completely proprietary software running on Windows, to fully adopting the embedded web browser tech stack for the UI, and JavaScript/TypeScript for applications and infrastructure services.
This talk will cover our approach to making Chromium and the V8 JavaScript engine the central core of the Bloomberg Terminal, and how we have been able to understand its architecture and performance characteristics in order to deliver the kind of near-real-time responsive UI the Financial Sector demands.
