Improvements in technology have helped this industry immensely.
The biggest advantage has been in overall weight and size of equipment. CDs are smaller and lighter than LPs. Laptops are smaller and lighter than CDs (and the dually CD deck system). IPods are smaller and lighter than laptops.
Mid-high and sub cabinets are molded poly and are lighter, smaller and easier to load and set up than their plywood bretheren. And they're active, too. You don't have to load amp racks.
Speakin' of amps, they're not left out. Class H amps have improved over the years. They're smaller, lighter and more dependable than their predecessors. And the switching noise issue has been eliminated as I understand.
These improvements in business equipment have helped this industry in several ways, most notably in load in, setup and load out time. Plus, the person or persons doing the work isn't beat to death before the show starts.
That said, all the technological advances in the world won't be able to replace that personality and love for entertaining. As Stu Chisolm has said, it may be music but it ain't me. Nothing can substitute for a professional entertainer. Jukes, ipods, rented PAs, what-have-you are machines. They're not entertainers.
It was once predicted that radio would replace public musical performances.
It was once thought that television would be the death of radio.
Some folks thought VHS units and rental tapes would make movie theaters obsolete.
People once thought that newspapers and books would be replaced by the Internet.
In each of these circumstances, new technology has melded with old to bring greater things to the consumer's doorstep.
We're currently wonderin' if iPods will replace paid mobile entertainers.
Predictions often turn out to be wrong.
