Reminds me of a relative's tale when he talked with a Japanese developer to find out why one product of their company was really slow at processing data and the other was much faster. Turns out they were developed by two different teams, one of which had the idea to use the GPU for acceleration. The two teams were neighbours in the same company building but communicated so little they didn't know what the others were doing, and how.
