As long as latency still matters. Gigabit wireless service can certainly be usable for a broad range of consumer applications, but you still have people playing online games, streaming, etc. that are heavily impacted by latency.
Personally, I wish I could get a decent 100/10 fiber connection in my area just for the latency advantages over DOCSIS alone (it takes roughly 10ms to even get out of my ISP's internal network onto their transit provider).
Modern LTE latency is comparable to DSL/Cable at <=30ms in many cases. Sure fiber latency is lower, but until that is available to the same amount of people as DSL/Cable the mobile technology will have advanced too.
Online gaming and streaming is totally fine over a LTE connection, the only problem is bandwidth caps. (This might not apply to professional gamers, but i consider those a niche)
It's totally fine for any kind of realtime online interactions though, unless you are a super competitive gamer, but even then many do not have access to fiber and still do well
Also note that i am saying "lower than or equal", my current LTE connection gives me 18ms ping to nearby locations, same as my cable connection.
