At last week's Microsoft Build conference, I attended the Hololens Academy -- a whirlwind effort to turn me into a master programmer able to create things out of thin air. It failed. Apparently it takes longer than an hour to teach someone who hasn't coded in decades to be a master programmer -- go figure. However, by the end of the class I was gleefully throwing fireballs at the heads of my co-wizards and their digital familiars. That took me down a Hogwarts-like path to the idea that doing things like Harry Potter did won't be that difficult.
