I don't think Donald Trump is a very good carpenter, or architect, if you want to be the Donald Trump of startups go to Wharton and then play the VC game.

You don't have to know how to code to do price discovery in tech. The cost of software is especially nebulous, and as PG recently talked about the vast majority of returns come from a few investments. I doubt very many buildings that Donald Trump put $18,000 into became $1 billion dollar buildings. Since the returns are concentrated and you have no idea which will be successful the strategy should be to put a little bit into a lot of startups, not learn to code and out compete your competitors by building software on a better cost basis.
