Seriously? As I write this, Microsoft, the largest purveyor of enterprise software in the world, is worth roughly $340 billion. Oracle? Less than $200 billion. Hell, Amazon, the company that Dropbox runs on isn't worth $200 billion.
You honestly believe that any one of those companies, none of which has been around for more than ten years, could reach a market cap of $200B within 5 years? Either you are incredibly bearish on the dollar or we are officially in bubble times.
