Keep in mind that the transition wont be from black to white or visa versa.. We're talking about a gradual change over a decade and a half a least. In the meantime there will be an uptake in jobs that support this type of automation.. physically building the thing, building the digital experience(Design, UX, Backend architecture, process, branding) as well as ancillary jobs like IT support, installation, IT, legal, union, whatever.

It will be less drastic than people anticipate, as always with automation/ai. Different jobs will become more available and (hopefully) the value of those jobs will increase. Manual/tedious jobs that used to be considered low-brow will hopefully become "artisanal" or appreciated, and fill the gap.

A butcher used to be a respectable profession that would earn an honest days living. Maybe now, instead of a butcher working for his employer (with a cashier, accountant, manager, sales person), they will operate as their own employer. Other micro-focused based companies will handle the other needs for a fraction of the cost.

In the end, efficiency prevails with capitalism and tech in general.. Having a population with a low work force seems both inefficient and impractical. Life will find a way...
