There is a valid criticism everyone can agree with, but the "solution" is really vague and hand wavy. There is basically no solution. This is a communication and people problem as old as social structures, and the only thing you can do is compromise based on your abilities, powers of persuasion and insight as to what works best for other individuals you're working with. If Yevgeney is good with CUDA, maybe ask if he also likes to only do CUDA stories, and also ask his teammates if they want to learn CUDA, and give them the opportunity to do so. It might be that no one does, and he's happy, or it might be there needs to be a switch, but you have to ask. This is not really about a democracy, it's more about communication and the optimal decision can be made voluntarily, or it can be "forced" because not everyone likes compromises.
