If you have a hard task to accomplish, and there's a way of making it substantially easier, the smart engineer is, frankly, going to take the easier option. They're only going to go with the hard one if that's the only hardware they have access to. Back in university we had to specify to the IT department that we needed Nvidia GPUs because people had done all sorts of cool things with CUDA that we could build on, and if we'd had to write it on AMD GPUs back in 2013 we would have burnt through all of our time just getting the frameworks compiling.
