It's happened many times before in many industries and it's still happening. Local butchers, greengrocers and ironmongers were replaced by supermarkets. Switchboard operators were replaced by electro-mechanical telephone systems, digital telephone networks, voice-over-data systems like ATM. Coal miners, steel workers, car making and shipbuilding and other manufacturing jobs have been offshored along with back-office jobs like medical transcription and paperwork processing. Elevator operators and telegram messengers were replaced by automated control and mail systems. Just about every manager used to have their own secretary. Then when E-mail came along, the managers discovered that they had to learn typing skills (to them, they felt they had just become "glorified secretaries").
Manual looms operated by four artisans in order to make one garment have been replaced by digital print looms that are large enough to weave carpets using patterns generated by Photoshop and require only one technician to supervise 15 machines. Print workers in newsagents (the guys who put boilerplate letters on drum printers and removed it again) were replaced by WYSIWYG systems overnight. Instead of the journalists writing shorthand articles and having them converted into boilerplate by the technicians, the journalists simply typed the text in. The print workers wanted that job as it seemed to closely match what they had been doing.
Ironically, a decade after the print-workers strike happened the Internet and the world-wide-web took off. If that had happened first, the print-workers could have migrated their skills painlessly to new industries. It would seem better to introduce technology to home users first, giving everyone time to make the jump.
