no single technology with dis-employ more workers then this one - no checkout clerks anymore at the stores, just roll your cart past the sensors, swipe your card, and go.
Their strike in So Cal proved they (checkout clerks) are too stupid to be employed anyway (most of them, anyway). I was amazed their brains could tell their feet how to move.
And self-serve is becoming more and more prevalent at grocery stores everywhere (I travel for business and stay at Residence Inn so I have seen them all the country).
But for every cleck unemployed there is a techy head that gets a job and at a higher pay scale.
Well perhaps not a 1/1 ratio
