Google Translate is arguably improving substantially with this update. The state of machine translation in general has already been better than Google Translate. The problem with the bleeding-edge systems is that they are not well distributed, no thought has been given to UX/UI, and the people who created them just want to finish their thesis and get out. Also, speed - the systems that eke out another few extra percentage points on accuracy tend to hoover up the CPU cycles, crushing their business case.
