Why we need a new kind of design discipline for on-demand platforms

Care to elaborate on what you mean by ‘scientific’?

If you using scientific to mean the interaction should be reduced to the two base variables - the good/service and the price, then I’ll strongly disagree.

The buy/sell transaction involves humans and thus involves literally thousands of different variables. To ignore or pretend those variables are of no importance is to essentially make the claim that being able to model the transaction is more important than the effects of the actual transaction itself.

I consider the market like the tendency for water to go downhill. By harnessing it, the developed world has become vastly wealthier than the rest. But if one ennobles the fact that water runs downhill (as Libertarians are wont to do), you are in danger of undo the legal, and even more importantly cultural, constraints (knock down the dams) that enabled us to make use of the market.

Those primitive commercial rituals embody many of the constraints that we place on the market so that as a society we can gain maximum benefit from the transaction.
