Knowing how to build a sucessful tech start-up and how to be a good president are two incredibly different skill sets.
I'm not so sure - both involve convincing a number of people to follow one's leadership and contribute significant funds/energy/time towards one's cause. Launching a political campaign is more similar to launching a big successful startup than working as a truck driver, or as an engineer, or really doing just about any regular job.
I just saw that Donald Trump is running for president. Which led me to the following thought: would any of the big names in tech have a chance at being elected president of the US? Elon Musk? Sergey Brin? Jeff Bezos? Reid Hoffman? Peter Thiel? Edit: Bill Gates?
Some follow up questions/thoughts:
Edit: hypothetically, if one of these big-name tech people were to try to gain political power, how should they go about doing so?
