Sure, AMD's got a great track record there. I mean, they've had...
FM2+, which got Kaveri and Godavari/Kaveri refresh (Steamroller and Steamroller)
FM2, which got Trinity and Richland (Piledriver and Piledriver)
FM1, which was a complete friggin' joke and just got Llano
AM3+, which got Zambezi and Vishera (Bulldozer and what Bulldozer should have been to start with, aka Piledriver)
AM1, which got Kabini. Didn't even get an update with Beema or Mullins. I think they added one new SKU at the top that was 50 or 150MHz faster lol
AM4 is NOT the norm. The only reason AMD's sockets appear to have better longevity is because of backwards/forward-compatibility during the AM2/2+/3/3+ era (fully dependent on BIOS and thus vendor support, incidentally) and because in recent years they stuck around so damn long because AMD didn't have any new processors. Seriously, Vishera on 990FX was AMD's de facto HEDT platform for FIVE YEARS. From 2012 until March 2017 when Ryzen replaced it (but even then not fully because it wasn't until later that we got Ryzen 3 to bury it at the same price). FM1 was just an embarrassment, to the point that AMD promised that the next-gen APU platform would get two releases... and it was Piledriver+TeraScale 3 followed by Piledriver+TeraScale 3 under a year later. And I've checked the docs I can find for all three platforms and I genuinely cannot figure out why compatibility was broken.
I'll also make the argument that offering backwards-compatibility with a motherboard is not a value-add. I am not buying X570 so I can use my shiny new Ryzen 7 1700 I grabbed off Ebay. However, I am buying a Ryzen 7 3700X so I can drop it in my old X370 motherboard. In a similar vein, I have no plans to drop an A10-5800K in my A88X motherboard because, well, Kaveri exists. But it sure would be neat if I could drop an A10-7850K in my A85X motherboard.
Oh and also keep in mind that AMD isn't officially supporting Matisse on A320. Did you build a budget APU system a couple years ago? Sorry, you need a new motherboard now! Yeah it's still AM4 but the CPU is unsupported for arbitrary reasons. Thanks to BIOS chip sizes, a lot of motherboards have just dropped support for Bristol Ridge as well. Sure, that's the old CPU/new motherboard combo that I just argued isn't a value-add, but it breaks compatibility. It throws a wrench in the "AMD is generous and does not make us buy new motherboards!" meme, but if you actually take a look at AMD's history, you'll realize that that's pretty typical.

AMD has had 3 sockets in 9 years, unless you want to count their low end platform s socket changes even though it is not the mainstream platform. The main issue is that the last socket, AM4, came out in 2016 and has been supported 3 years now and looking to support another year. Intel hasnt kept anything that long.
And this is looking extra far back just to get the socket count of both companies up. If we look in the last 5 years only:
Intel has had 3 sockets in the last 5 years (Z97 through 300 series)
AMD has had 1 socket
Instead of counting sockets, we can count microarchitectures.
AMD has had 8: K10, Bulldozer, Piledriver, Steamroller, Excavator, Zen, Zen+, and Zen 2
Intel has had 11: Nehalem, Westmere, Sandy Bridge, Ivy Bridge, Haswell, Broadwell, Skylake, Skylake-SP, Kaby Lake, Coffee Lake, and Cascade Lake
Intel has had more sockets because Intel has released more actually-new CPUs. AMD released a refresh of Vishera more than three years after its initial launch. This isn't like, I dunno, an i7-6700K to an i9-9900K where it's a similar core but larger. This is the exact same silicon but overclocked a little out of the box. The Internet would not shut up about it if Intel did this with Skylake today.
