Mike, As someone who works in the cellular industry, you're actually kinda right, 5G is a lie. 

Ever since 4G LTE deployed Gs are no longer relevant. LTE stands for Long Term Evolution, meaning it is the core that is supposed to last for a long time. 

3GPP released LTE in 2008 and creates a new incremental cellular release roughly once every 1-2 years. 

Since LTE there have been some improvements for consumers but most of the improvements are targeted towards industrial features such as IoT, vehicle-to-x, network slicing, and indoor positioning.

4/5G is perfectly capable of supporting people's day-to-day mobile broadband needs. The real challenge is convincing telecoms to meaningfully deploy it everywhere we go instead of "innovating" by executing G++ every 10 years.
