My parents were mathematicians. My mother helped code one of the first stored-program computers — the Manchester Mark 1. They taught me that when you program a computer, what you can do is limited only by your imagination. That excitement for experimentation and change helped me build the World Wide Web.

I had hoped that 30 years from its creation, we would be using the web foremost for the purpose of serving humanity. Projects like Wikipedia, OpenStreetMap and the world of open source software are the kinds of constructive tools that I hoped would flow from the web.

However, the reality is much more complex. Communities are being ripped apart as prejudice, hate and disinformation are peddled online. Scammers use the web to steal identities, stalkers use it to harass and intimidate their victims, and bad actors subvert democracy using clever digital tactics. The use of targeted political ads in the United States’ 2020 presidential campaign and in elections elsewhere threatens once again to undermine voters’ understanding and choices.

We’re at a tipping point. How we respond to this abuse will determine whether the web lives up to its potential as a global force for good or leads us into a digital dystopia.
