How can you not see that this time its actually different? The very need for labor is being obviated. Every technological change we had before still required a need for labor often an massive need that justified an entire city population. That is the difference. For the first time in human history, economic output is being severed from requiring maintenance of a labor pool. Considering we are that labor pool, things do not bode so well for us. As you state, look at the relative lack of abundance of candlestick makers and horeshoe makers and basket weavers and other colonial jobs. We are essentially making ourselves extinct and we don't even realize this.

There's an off-color joke that could be made here but the real question is the speed of change - we gloss over it but there have been major changes that took centuries, and others that were quite fast, this one seems to be closer to the fast end.

Yes and? You'll be shocked to know that pretty much none of us were alive in colonial America.
