We have palm-sized devices that can provide you turn-by-turn directions to friend's house, while streaming music over a (semi-)pervasive data network, and keeping you in constant communication with everyone you know (eg. IM, etc.). They can continuously update a map with your location, for all to see, and query what more or less amounts to a global intelligence for information on pretty much anything. Remember the hitchhiker's guide? The thing that was complete fiction in the '70s? We've developed methods to selectively suppress gene expression (RNAi), which is already paving the way to new disease treatments and cures, and even more effective genetic manipulations. Maybe soon we'll be able to completely change our genetic makeup with a designer virus. Transistors are now only a few atoms thick, and still growing smaller. We've finally discovered the memristor, which should provide even more complex circuits at a fraction of the size (memristors are physically less complex than transistors) -- we're configuring components at an atomic level. How can you seriously claim that today's technological progress doesn't stand up to that of the 1920's? Consider my mind boggled.
