McLuhan's ideas get written about so much, but nobody does it nearly as well as McLuhan himself. His 1969 interview with Playboy I think is the best primer:<p><a href="https://www.nextnature.net/2009/12/the-playboy-interview-marshall-mcluhan/" rel="nofollow">https://www.nextnature.net/2009/12/the-playboy-interview-mar...</a>
To me, the smartphone conditions us to experience relationship with other people through single-finger swipes.<p>There are many other positive effects that smartphones bring but I don’t think we’ve fully internalized the negative side effect of the constant dopamine Drip of social media.
That was a worthy exercise which explained well the concepts used.<p>Unfortunately, either the tools or the author were not up to the task of providing interesting insights.<p>(IMHO, YMMV, etc. Also, apparently undergrad work, from the pub header.)
This reads like a last minute research assignment with a minimum length requirement. The ‘tetrad’ diagram is probably one of the more distracting and less useful paths to understanding McLuhan. I encourage anyone interested in the topic, or McLuhan, to look elsewhere.
