I think this has been shared before. An article by Clayton Christensen: "Consulting on the Cusp of Distruption" [long].https://hbr.org/2013/10/consulting-on-the-cusp-of-disruption
Not sure that it is worth reading the whole piece as not much to learn in that logically everything industrial is going to be blown-to-bits at some point. The interesting money is more to do with when, how and why?
A couple of little extracts that made me smile though are worth sharing: "Management consulting’s fundamental business model has not changed in more than 100 years."
The stranglehold of the utilization model ;-)
and: "... two factors—opacity and agility—have long made consulting immune to disruption."
I can imagine the an exponential unfolding is overdue on both of these points. Intuitively inevitable but like the Snowden awakening some major failures will perhaps have to shine a light on some poor practices...
