"History shows that just as you get settled with such a device, technology moves on so much that the underlying bus becomes useless and out of date."
Depends on the cost of frequent change. In the commodity Wintel market, the modern IT department's status tends to depend on increasing their budget year on year, buying the latest shiniest because the directors wanted it.
In the real world beyond Dell Intel Microsoft, where computers are sold to organisations who want them to do a specific job as part of something they make or do, and don't need/want unnecessary change, different rules have applied for many years.
Basically you've just explained the reason why the PCI Industrial Computer Manufacturers Group was formed in the 1990s. You probably won't have heard of them, though some readers may be aware of things like VMEbus and CompactPCI.

Modern Raspberry Pi isn't PCI based and isn't quite industrial enough for everyone but it ticks a lot of other boxes as a low cost (to design around, to build in, and to support for a reasonable lifetime) embeddable computer system. It's not far off being the new "industry standard" for much of the non-Wintel market.
Anyone still looking at Wintel for the market sector these Pies sell into needs their head examining.
