From Natalie Wilson's dissertation of 2011- very interesting

Possibly the most famous critic of the impact of new technologies is Nicholas Carr (who I previously quoted). Carr’s most well-known and influential text on the subject is 'The Shallows: How the Internet is Changing the Way We Think, Read and Remember' (2010). Although his argument regarding the damaging effect technology is having on our capacity to think and concentrate is quite contentious, he is not the first person to negatively chart the impact of new technologies. Socrates expresses similar fears when he condemns the invention of the alphabet by Theuth a famous old God:

'And in this instance, you who are the father of letters, from a paternal love of your own children have been led to attribute to them a quality which they cannot have; for this discovery of yours will create forgetfulness in the learners' souls, because they will not use their memories; they will trust to the external written characters and not remember of themselves. The specific which you have discovered is an aid not to memory, but to reminiscence, and you give your disciples not truth, but only the semblance of truth; they will be hearers of many things and will have learned nothing; they will appear to be omniscient and will generally know nothing; they will be tiresome company, having the show of wisdom without the reality.'
