Are Humans Becoming Obsolete?

It occurred to me today that we humans are becoming more and more unnecessary for each day that passes, and it's getting a little disturbing. We interact with one another less and less as time progresses thanks to voice mail, answering machines, auto dial, atms, etc, etc, etc. We may not realize this, but it's happening. Every day in fact.
I myself work in call centre, and have actually had people ask if I was a computer. I don't think I sound like one, but really, how often does it happen when you don't get a computer voiced call or have the annoying occasion of dealing with those damned computerized relay systems, "press 1 to access this option, press 2 for this option", blah, blah, blah. Where in the hell is the digit I push to speak to a bloody human being?
It's everywhere, from banks to department stores and so on. We no longer communicate on a personal level. It's a machine to machine world. I personally haven't seen a bank teller for months, I don't speak to a receptionist to make doctor's appointments, hell, you can even order a bloody pizza over the Internet!
Now the latest thing is self-serve checkouts in grocery stores. It seems we don't have to deal with another single human being to conduct out daily affairs. We don't even manufacture anything by human hand anymore.
I remember back when I was a kid and the first completely robotic produced automobiles were made. Some thought it was an abomination, others thought it was the cat's ass. I really couldn't have given a rat's ass, 'cause I was only 8 or 9 yrs old. Well, the auto industry embraced this new technology, and boom! Thousands of auto workers laid off. Who needs people when computers can do the job? You don't hafta pay a robot! Even before then, machines have taken over pretty much everything humans used to do. Food stuffs, furniture, some forms of clothing, musical instruments and even gas pumps. Self serve combined with pay-at-the-pump means you don't even hafta go into the store to pay for the gas you've jes' filled up with. We jes' seem to be less and less necessary.
Now, they say that the automated world we live in was created for greater ease in regards to manufacturing. It's much more efficient and cost effective. Why pay for a 100 workers to labour for 8 hrs. when you can automate your business and run it with 10 people instead? Who cares about the rampant, high unemployment rate or number of people dependent on social assistance? Large manufacturers don't.
So what do we do? What can we do? The answer unfortunately, is nothing. We little folk can't change the way our world has become, no matter how sick and tired we are of being on the phone with the bank for and hour, trying in vain to speak to an actual human being. And besides, do we really wanna wait more than 10 seconds for that bottle of coke to come whizzing down the assembly line or speak to the snotty bank teller with far to much lipstick on her teeth and reeking of cheap perfume? Prolly not.
So, I guess we jes' suck it up and carry on. Hopefully we'll be useful again some day, but until then, press 9 to speak to a computer.
