the flawed assumption that we can't work on more than one problem at a time.
that throwing all of our resources at a problem will speed up the solution to that problem without reaching a point of diminishing returns of investment.
that all scientist, engineers, researchers, doctors, etc are interchangeable and are equally motivated and capable to productively research problems in unrelated fields and that if their chosen research were de-funded and were to be moved to another field they wouldn't just quit and do something they are more interested in.
ignoring that knowledge gained in one field might also advance progress in another.
* The project is using a non-negligible percentage of all resources available to the problem space
* Everyone agrees on what the problems are
* Everyone agrees on the priority ordering of problems that need to be tackled
* There isn't greater waste or opportunity for resource allocation from other projects first (e.g. video game dev or plastic surgery research)
* it's the responsibility of everyone to always be focused on working on the highest priority problem on some global list of problems.
It's very flawed logic IMO.
