In college, I was always the first one out of my friends to “get” a concept, like fast Fourier transforms, anything with signal processing or even coding or any labs we had to do etc so I would spend time teaching them in the library. However I never did any of the exercises, mostly due to laziness and not arrogance. They would get A’s and I would get C’s and D’s.
I emphasize this story to my kids because knowing isn’t important because everyone eventually figure it out. It’s the ones who can do the problems and get good marks that succeed in the end.
Lyft wasn’t bought 2 years ago at $5B. What makes anyone think that they would pay $25B now? The only difference between two years ago and today is increased market share which is at best ephemeral. It can be taken away as easily if competitors drop their prices.
