If you read some of the comments on the article they simply cite automation techniques that are focused on decreasing costs for merchants like grocery checkout. It's true, these are arguably worse than the human alternative. However, this is extremely short sighted as in time we will have automation that is superior to the human alternatives. Grocery checkout will be replaced with self-stocking kitchens (which decide on a menu based on the FitBit in your blood stream) delivered by self driving cars. Instacart is a good example of the "hack" version of this.

With that being said, I think there'll still be room for the "human touch" in leisure oriented businesses like restaurants or high-touch pricey services like high end wealth management.

You can see that this article appears to have an anti-futurist, anti-technology sentiment. Its opinion represents the vast majority of the world's view which tends to only forecasts out 3 to 5 years out. Significant change is a scary concept especially to those subject to the change. I believe that wealth disparity will continue on the trend that it has been and likely "get worse". But it is my hope that someday a high standard of living will be so affordable that the poorest will have a very high quality of life.

Currently, we technologists are building products that improve the quality of life of the wealthiest 25%. I see this as a good testing ground. Take a page from Tesla's strategy with products and services for the wealthiest to later understand how to bring those products/services to even the poorest.

A note to the technologists/futurists here: as much fun as it is to be "disruptive" especially to large enterprise and put ourselves against them, this is not the most pragmatic approach for middle class jobs. Instead, let's emphasize that automation/technology will ultimately improve everyone's lives so that the middle class lifestyle will be the new "poverty". That's the type of "poverty" I'm happy with.
