I can tell from the obvious historical errors I've seen in them.
@skeeter Truth to tell,I fell kinda sorry for them. They grew up as geeks and got advanced geek degrees,and now,after spending all that time,money,and work to get those degrees,some people that park cars for a living earn more money and have better job security.
I have several friends who had teenage children that were telling me 10+ years or so ago that they didn't need to learn how to cook,fix cars,build houses,or any other "menial trade because I am going to get rich designing computer games."
Uh,huh. At least one is SELLING computer games at a mall software chain store,and I guess,"living the dream".
Computer geeks have to be some of the lowest paid technical specialists on the planet,now.
