1.	Even so, some trends are real, and almost all trends have some value in them, but it's not always where it seems to be.
2.	The Web is real. Its revolution is that it enabled power users to become developers, and writers to become publishers. A network programming language with a very easy ramp. We had been looking for this, and hats off to Tim Berners-Lee for finding the magic formula.
3.	Another trend that's real -- GUIs. How many people use command-line interfaces these days? A very small minority. At one time almost everyone who used a computer typed commands on a virtual line printer, or "glass teletype." GUIs, in the form of Mac and Windows, had staying power, obviously. They changed the way we work with computers.
4.	Even Java and open source have real value. Java has become a popular server-side programming language now that it's no longer a religious movement, and open source has focused attention on the basic generosity of programmers, but it isn't as exclusive a club as the promoters would have you believe.
