Honest abstractions

Numbers feel very simple and obvious to us. But they only exist because people observed the real world, spotted patterns in it, and built abstractions to represent those patterns.

Tom Stuart talks about honest abstractions inĀ A Lever for the Mind.


Currently CTO at Mast. Formerly engineering at Thought Machine, Pivotal. Makers Academy alumnus.

I've pledged to give 10% of my income to highly effective charities working to improve animal welfare. If my startup is successful, I hope to give away much more.

Also founded EA Work Club, a job board for effective altruists, and Let's Fund, a crowdfunding site for high-risk, high-reward social impact projects.
