China's track record with free speech makes the implications of completely bypassing any human 'journalist' kind of scary. I guess it's always been possible, but damn.
If it gets cheap enough, it will likely happen elsewhere. Onscreen talent is an expense that a lot of media companies would probably happily get rid of. It doesn't mean the reporters go away, but a universally and perpetually attractive, easily changeable, contract-free and salary-free anchor would be a bonus for any news company.
It could even spark new industry as companies arise to create avatars for other public-facing entities where a real person is not required, like corporate PR spokespersons.
Hollywood has already started down this road by creating virtual stand-ins for deceased actors - there's no reason to consider that they won't just create one from the whole cloth within a few years.
It might not happen, but don't be surprised if it does.
