Why not? When we moved from 3G to 4G I felt like it was kind of useless, but now that I have it I definitely enjoy all the things that become possible with it (lower latency everything, mostly). It was the same way moving from ISDN to cable. It's never bad to have better stuff - you'll find a use for it even if you don't have one now.

> can you explain some concerns you might have about 5G

Frankly the only real and reasonable concern to have is that there are very few engineers that roll out 5G networks that aren't Chinese. I'm not opposed to China, but I am opposed to a country's entire infrastructure being built and maintained by another country (that may want to use that to exert political pressure some day).

> there is a tendency by the group to form an echo chamber

In this case I really don't think it's that, it's mostly that you posted information that's just wrong and then you retreated to a (frankly lazy) defense as to why you're spreading misinformation. It makes you come off as the kind of person that's really unpleasant to talk to, because the lies tend to be so sticky and pervasive. It's exhausting to have to revisit every component of what you know just because someone else couldn't be bothered to figure it out for themselves.
