What will our daily workflow as programmers look like a year from now? If AI coding assistants improve at their current pace, who knows. But our theory is that the close reading of code will be a critical skill.

In the distant future of 2027, rather than programmers we may be mostly program readers. How do you become a great program reader, especially if you're just starting out in software? GitGuessr is a playful way to train your code reading skills for the AI era.
