I'll admit I've quite understood this ambivalence about WAN links, and particularly not on tech sites. Consider: would you find no different on your LAN going back to 10Base-T, or being restricted exclusively to 802.11a-1999 for all networking (no wired at all) in a spectrum crowded environment, and thus with double-digit latency at all times? Or is gigabit or even higher actually useful in a variety of ways? How about for your persistent local memory speed, is SSD or even modern HDD of no benefit vs something on PATA or IDE or whatever from the 90s? I don't think I'm going out on a limb in saying that yes, having more bandwidth available has and continues to be quite valuable.
So then take that and remember that there is zero fundamental difference between LAN and WAN except latency based on distance and even that isn't that restrictive on Earth, particularly within a country. It's about 93 miles per millisecond RTT under ideal vacuum/air/photonic-bandgap fiber, or 70% of that in standard optical fiber, so 1/90 of a second say could easily be enough for a round trip to anything within a good 300-500 miles. And at a minimum, any application done on a LAN right now could apply directly. For a lot of the public for example thin-ish clients might actually make a great deal of sense for their "personal computer", just as it long has for businesses or certain home users right now, if only they had reliable high bandwidth connections. A lot of things that many people currently centralize could be decentralized again if it was ubiquitous that the population just WireGuard into their LAN from anywhere within a hundreds of miles or more and have an experience essentially the same as being on the LAN itself.
I mean yeah, we can imagine all sorts of future AR/VR applications or enhanced privacy via onion routing and the like (essentially being able to burn some spare bandwidth on it for the same experience as present) and the like too. But is it even necessary to imagine that far? We use LANs right now, and that for most people there is a dramatic split in their LAN/WAN experience isn't down to physics (most people aren't going more then 500-1000 miles away with great regularity).

A repeated dream. In reality thin clients suck even on a LAN. Remoting from a Windows PC to a Mac Mini sitting right next to it had unacceptable latency.
Which is rather confusing given that modern machines can encode video at over 60fps....
Same OS to same OS is better, but not great. Every few years someone comes along and tries to deploy thin clients, and it never takes off en masse, good enough for a few limited scenarios though.

It's the tech you're using. It's most likely streaming jpeg images.
Try, for example, Steam Sharing, but share something like notepad. You can minimize it and it will work as remote desktop. You'll find yourself on another computer with virtually no latency, as if it is native.
