THE TYRANNY OF THE ENTERPRISE LAPTOP

Every (networking related) event or conference out there has at least some talk about automation - with the audience divided into people who are politely interested, because they have been doing it for years... and the others who never wrote one line of code in their life, watching with desperation in their eyes yet another presentation they don't really understand heralding the end of their careers as they know it. There's a lot of FUD (fear, uncertainty and doubt) out there and it's driven by the "expert tech journalist" mouthpieces and non-stop marketing machines, but as with all things the noise has an effect on people.
