So you think Technology was invented yesterday. I did a Technology degree in the 60's and have worked on Technology all my life. Have you heard of a little company called DEC that had PDP's 8 in the 60's and the PDP 11 in the 70's have you heard of Prime, Honeywell, Wang and IBM with main frame and mid Range computers. Have you heard of a programming language called Cobol its been around for 50 years.
When you work in Technology all your life its very easy to keep up with developments. My first cell phone was the Motorola Brick if you know what that is, you carried it in your briefcase not in your pocket.
