Here we are again, thirty years after I was taught the "waterfall" paradigm at business school.

When asked about "customer satisfaction" we were told, awkwardly, that became "political"

The paradigm did not survive its encounter with reality, and I do not think this one will either

The "only" 175% increase in productivity is very impressive, and seems realistic to me, when you remove the chores of writing code (thank you to coding agents)

What you build is still very dependant on what you need, and you do not know that until you build it

It is a paradox only for the "waterfall" paradigm. We rejected it, in the 1990s for a reason

It did not work
