When the iPhone came out, I thought it was a joke. Amongst its substantial list of deficiencies it had no apps, couldn't multitask, lacked a keyboard, had a very low resolution screen, and had no GPS. Despite the hype surrounding it, I wasn't interested in the least. I don't remember exactly how I felt back then, but I wouldn't be surprised if I predicted that it would fail.
Steve Jobs was a smart man. The GPS, keyboard, and all those "critical" features I mentioned didn't accidentally get left out. He left them out deliberately. Why? Because he understood that there were only a few key aspects of the phone that would determine its success, and he focused on them to the exclusion of everything else.
Back then, smart phones were easy to use if you were a nerd, and difficult to use if you weren't. They had ugly interfaces upon which a gaudy layer of polish was sometimes applied. They were slow and clunky. The iPhone, on the other hand, was simple to use, snappy, and looked great. Anyone could use it easily, and would enjoy doing so.
I've been saying that college is obsolete for a very long time. I dropped out in 2000, because even back then I could see that it was a really poor value proposition. I didn't predict this because I'm some crazy genius, but because I'm willing to discard emotional attachment and stare plainly at the facts.
School is outrageously expensive, leaving graduates with a debt (or net expenditure) of tens of thousands of dollars-- sometimes even one or two hundred thousand. There are some things that are worth that amount of money, but for many people school isn't one of them. In fact, apart from very specific cases, I think that school is a bad thing, not worth doing even if it was free.
That's not to say that school has no benefits whatsoever. It does, and although I left with zero additional skills after my three semesters there, I had a good time and benefited from the social aspect. The problem is that you can't just compare college to doing nothing at all. You have to compare it to what you COULD have done.
