Today Twilio is down 37 percent in a day today whoa but guys this is just math you know it's not a judgment on any of these companies it's just pure math. I think the elon action this week really sets a standard he shows the entirety of Silicon Valley that you can cut deep and you can turn a profit and you can do it fast. It could set a new standard for how folks are managing this jack welch used to in his management principles recommend dropping the bottom 10 percent of people every year. When do google and facebook stop this i mean if you look at the number of employees being added it is truly extraordinary.
