THe really scarry technology that is upon us is black box voting. Please see blackboxvoting.com and http://www.andystephenson.com - the candidate running for WA Sec. of state and against paper trail free, hackable elec. voting machines. US elections in GA were already stolen using this technology.

RFID tech is great - products will be able to move directly from Chinese and US prison labor camps to store shelves without ever needing to be handled by human hands. Sensors can track the merchandise, machines can move it, and East Indian maintained computer techs can handle the accounting. The increases in efficiency will be enormous. Walmart will be able to greatly reduce its labor problems. Male retail labor will be freed up to do more extensive and complex landscaping on the growing estates or get jobs helping people like Prince Charles go wee wee. Female retail workmeat can become "massage" therapists, waitresses or find other work satisfying the appetites of the tiny class of super wealthy. Once we install properly oriented RFIDs in turkeys, we can free up slaughterhouse labor because machines will be able to do a wonderful job of handling the animals. Geez, we can even implant RFIDs in people - so they can be managed as needed.
There does seem to be a limit tho, as increases in efficiency lead to greater consumption of natural resources and production of pollution (causing problems economists like to refer to as irrelevant externalities) there will be more global warming, desertification, soil salination,
