Excellent question
Jamie Bartlett at UK Telegraph asks a deeply important question. Why do radical politicians like Corbyn and Sanders completely ignore the problems of technology? Bartlett includes the more obvious stuff like self-driving cars, and names several that we don't normally worry about:

The rise of machine learning algorithms that, according to author Andrew Keen, will soon replace a huge amount of skilled middle-class jobs like teachers, lawyers and authors – decimating what he calls "the 20th Century Meritocracy", that has been the backbone of modern democratic societies.

Or the fact that information of all types – secrets, copyright, creative content, illegal images – is becoming increasingly more difficult to contain and control.

Or the dangers of the centralisation of power of the internet into the hands of a very small number of large companies based overseas, and what that might mean for job opportunities, access to information or who controls the public space.

Well, the last item answers the question. Fans of Corbyn and Sanders include lots of Luddite Localists and lots of Tech Tyrants. Luddite Localists don't have millions. Tech Tyrants have millions. And Tech Tyrants are not going to oppose the listed tendencies because Tech Tyrants ARE the listed tendencies.

Corbyn and Sanders know where their money comes from.

This goes beyond technology itself. Corbyn and Sanders are not going to oppose immigration and outsourcing because Apple and Google depend on cheap Hindoo programmers and Bangladeshi slave labor.

Tech wouldn't exist without slavery.

Meanwhile, Corbyn and Sanders join All Respectable Humans in tearing down Confederate flags and statues of anti-slavery Robert E. Lee and every word that might possibly contain the evil letters S-O-U-T-H. Like Lincoln, the modern industrialists need to eliminate all traces of Slavery Conducted By The Wrong Sort Of People, in order to clear the scorched earth for Slavery Conducted By The Right Sort Of People.

No, wait. A minute ago I wrote 'Tech wouldn't exist without slavery.'

Dead wrong. Exactly diametrically wrong. Railroads, Lincoln's bosses, used Chinese slaves to build their tracks. Just like Lincoln's modern admirers. But after railroads we have a long string of new technologies that grew and developed WITHOUT slavery and exploitation. Telegraph, telephone, automobile, radio, petroleum, aircraft, and pre-PC computers grew explosively and PROFITABLY without any Chinese or Hindoo slaves.

In precise fact those industries were FAMOUS for GOOD WORKING CONDITIONS AND GOOD WAGES. Henry Ford, John Patterson, E.W. Marland. All were advocates of Social Economics, now abandoned in USA STRONG but moved to Korea and Japan with great success.

Constants and variables. It's not TECHNOLOGY that depends on slavery. It's GOOGLE AND APPLE AND AMAZON that depend on slavery. Their share-value model requires zero labor costs.
