If anything I see increased convergence between connectivity methods not any one technology supplanting another. Making your service plan able to connect the user from Wi-Fi + Celluar + Satellite when they are indoors, in a dense area, or far away will be able to deliver a far greater experience than locking into any single technology both in coverage and performance.

We already see this kind of thing already with T-Mobile + Starlink, Home internet providers bundling phone plans and allowing you to roam to other networks, traditional cellphone providers hopping on board Wi-Fi calling support, and Apple + Globalstar.
