I'm always amazed at how Peter Norvig continues to create the kind of content that a top grad student would do, even as his career and rank in the industry has skyrocketed. Back in university and grad school I would write tutorials and post them online (and still get thanks from random people many many years later). I would explore random interesting subjects and dive deep. I would constantly publish code and demos, etc. As my career grew, one of one these started to fall off. I look at my peers and it's the same story: they were all vibrant hot-shots in their early-mid 20s, and now are just weighed down by the teams and projects they manage. Peter is an inspiration. I will ponder this...
