Yee, Li-Fi’s been around for a while now, plus IEEE 802.15.7 has been on the books for about five years. Though this time it’s in the big famous .11 one so that’s kinda cool. Light Communication is super fun, but outside of a few very niche industrial settings it’s not going to be a huge industry-changing revolution. But pretty lights go bleep bloop so I like it anyway :3 ^{except this is IR so boo :P}
