This is spot on. Load times do not matter for the kinds of apps that:
* Are exclusively loaded on high speed internet in corporate networks.
* Have a high hours-of-work-per-page-load count.
* Update infrequently.
We're engineers, or at least we like to call ourselves that. Engineering is the process of gathering requirements and building a system that meets those requirements on time and under budget. If your requirements include being able to serve users on 3G networks or users who only load your site in order to read a single piece of content per day, yeah, optimize your load times. But don't attack other engineers for failing to live up to your app's requirements.
