A surprising story from the AI industry: **Boris Cherny**, the head of Claude Code at **Anthropic**, briefly left the company to join **Cursor**—and then returned just two weeks later.

In this video, we break down why Boris made the move, what he discovered after joining Cursor, and why he ultimately decided to go back to Anthropic. While he admired Cursor’s product and team, he realized something important was missing: the mission.

At Anthropic, the focus on **AI safety** drives everything. For Boris, that shared mission was a major reason he joined in the first place. Without that deeper purpose, even working on an exciting AI coding product didn’t feel the same.

His quick return highlights an important lesson in tech and career choices: sometimes the **“why” behind the work matters more than the work itself**.

Was this the fastest job reversal in AI? Maybe. But it also raises a bigger question about purpose, mission, and what really keeps people motivated in the fast-moving world of AI.

What do you think — is mission everything, or is it overrated?

To find three equivalent fraction for 3/5, we can multiple 3/5 by the equivalent of 1/1. For example:

3/5 x 1/1 = 3/5
since 1/1 = 1 and multiplying by 1 does not change the value.

If we multiply:

3/5 x 2/2 = 6/10

Here again, since 2/2 = 1 we aren't changing the value, just the way it is written. Both 3/5 and 6/10 are equal to 0.6.

We could also multiply by 3/3, 4/4, 5/5 and so on to find more fractions that are equal to 3/5. As long as we are multiplying by the equivalent of 1, we'll get a fraction that is the same as 3/5.

Who can engineer the best slime? Beginning with a preset recipe, students make slime, observe it, and then decide on what and how they want to improve it, such as making it stickier or less sticky. Students then make their updated slime by implementing the changes they want to make. They are introduced to product optimization, material science and polymer engineering.

Plants eat sunlight and air to make life. But the key enzyme behind it all, called rubisco, isn’t actually all that great at its job. Let’s talk about how photosynthesis really works, why oxygen isn’t coming from where you think, and whether we can fix the biggest flaw in one of Earth’s most essential processes.
