I don't think this is a candidate to replace wifi. But if it's cheap and becomes ubiquitous (unlikely) it would make wifi a lot better.
The advantage of the visible light approach is that it doesn't reach through walls.
It's inherently very dense, and can provide users in its footprint nearly unlimited bandwidth. If it reaches only 50% of users in a classroom or office building, then those 50% of users will have very fast connectivity, and wifi will be twice as fast for everyone else.
