Slight criticism: from the given examples, seems obvious that type 2 already knows the solution proposed by type 1 (apparently it was a very easy one), and also does one step further, asks how it impacts the users.

And then, in this case: it's really a continuum, and obviously it's not two types but just worse and better developers.
