Why is Cisco pushing multi-gig access switches with 25/100gb uplinks? Just who is this supposed to be appealing to?

I work with several large enterprise customers and most of them are getting rid of their onsite data centers. They are either moving all their applications to cloud providers, moving their DCs into colocations, or doing a mix of both. This means that soon enough, all client-to-server traffic will flow over the WAN, with the campus essentially becoming one large remote-site. As for client-to-client traffic, I won't say it doesn't exist, but it is relatively inconsequential. VoIP RTP sessions don't take up much bandwidth, and the same goes for Machine-to-Machine IOT traffic.

Now that I've established what current and future traffic flows look like, let's talk about WAN connectivity. Outside of DCs, none of my customers have any circuits larger than 1gb; in fact, line rate, dedicated GigE circuits are still pretty rare. As DC sites, they all have 1gb to 10gb circuits for branch WAN aggregation, centralized corporate internet/cloud access, and data center interconnection. But what will happen to these sites when they no longer host DCs or provide branch WAN aggregation? Well, I fully expect my customers to decommission their 10gb circuits and move to 1gb or even 500mb services at their campuses.

We're looking at a future where (1) all substantial traffic flows will be constrained to the size of WAN links and (2) WAN links at former "hub" sites will be sized only based on the needs of local users. So why is Cisco pushing access-layer switches with multi-gig access ports and 25/40/100gb uplinks? It seems to me that 1GigE access ports and 10GigE Trunks are still more-than-sufficient for today's requirements. Now I get why someone might argue for 25gb uplinks - switches don't have nearly the same buffering capabilities as routers, so you want your campus backbone to be oversized. But giving a user or a single AP a switchport that's sized like a WAN circuit in a world where everything goes over the WAN? That sounds like nonsense to me.

I get that there's product lifecycle to consider, but until you can get a 25GigE circuit for the same price as today's 1GigE's, (not something that I see happening in the next 5 years...) this whole technology and "push" from Cisco seems pointless to me. What do you guys think?
