Not the addressee but it&#x27;s spectacular all around.  There are a few classes that have a reputation for being poorly designed&#x2F;maintained and a few with somewhat &quot;unreasonable&quot; time requirements (ie 50 hours a week for a single class).  There are classes where you only interact with TAs&#x2F;students (which is fine) and some where the professor is seemingly on a 24-hour modafinil drip, there to answer any question posed at any time.<p>For the most part it&#x27;s intensive and immersive with enough learn-at-your-own-pace aspects to accommodate full-time jobs, families, hobbies, etc.  I feel like I come away from every class like I&#x27;ve actually learned something that&#x27;s embedded in me.<p>Udacity is what it is: a platform for watching videos with some minor ability to interact with coding examples &#x2F; quizzes throughout.  I have no issue with it, but agree that most of the meat of the courses come from other parts of the classes.<p>My hunch here, through Thrun&#x27;s quotes and some in this, is that there were some aspects of CEO at this level that really didn&#x27;t appeal to him.  How many CEOs truly get to be personally creative in their position?
