Consistency is a requirement that holds us back deeply. Implementing constency with eventually voted know-all masters are also holding us back. Looking at this makes an engineers heart cringe. In fact the current architecture is only slightly better than what we had in 2005, more than 10 years ago. And if it runs not on google or amazon clouds, and therefore on UNRELIABLE networks, the voting itself can fail and you have a centralized system without center. And while we claim that we need a central point of knowledge that is at sync throughout the whole system, the whole world AROUND the IT works completely without being in sync and completely without knowing it all (sometimes even having no knowledge or assumed but wrong knowledge), at a scale that IT systems only to some degree come close to nowadays.
