That is introducing a false strawman choice.
if you shoot weddings, two cameras and two photographers is highly recommended.
If it is a job, then perhaps having an assistant carrying another camera set-up will work?
These two choices get you two different things. If you have a single body and it goes bad, then you lose the ability to take additional photos with that camera. But with the single card, if that goes bad then you lose all the photos you've shot up until that point.
You don't mean smart photographers in general, do you? I am guessing you mean certain professional photographers. I have done just fine with one one card and two two card cameras, used separately, my whole digital life. And, before that, a one roll of film camera. I have a preference for avoiding worst case scenario thinking or, as AE Neuman always said: What, me worry? I suppose that would change if I were preparing for battle.
--As the saying goes, "Two is one, one is none" (often used by the Navy SEALs). It means if you only have one of something, it's as good as having none (if that one item goes down). So you need two of everything, whether it be a weapons, or cameras, or memory cards. If you have a single camera and it goes bad, you're toast. If you have a single memory card in your camera and it goes bad, you're toast. If you have a single gun and it goes bad, you're toast. You need redundancy! Two is one, one is none!
There is one shoot I do that I do about 150 portraits.

If dual slot so important, it so be basic requirements of camera. Not only for pro camera. For example，travel/entry level camera should has dual slot. We can't ask someone go back to travel destination (especially oversea country) to take again travel photoThere is one shoot I do that I do about 150 portraits.
I could swap out the SD Card throughout the day so that if an SD card got damaged, I would only miss a portion of the shots. And I guess I could then go back to the organization and tell them that I need to do certain portraits again because of a damaged SD card.
But . . . that would add complexity to my process. And if I have to go back to the organization because of a failed SD Card, it would be a pain in the butt. When it is so easy to simply shoot to dual cards.
And . . . sometimes I do a group shot of about 150-175 people in the shot.
If the SD card failed that had that shot on it, it would be next to impossible to get all those people to come back for a make-up shot.
Since I have 2 cameras with dual SD cards, it really is such a simple thing to shoot to two cards and reduce the chance of having to go through the pain of asking people back to take their pictures again.
It is such a simple thing to do.
I don't really understand why anyone is saying that they don't see the value in cameras with dual slots. LOL.
Take care & Happy Shooting!

Since dual slot (only mirroring backup to dual card) should be not much costing, dual slot should apply to all entry/medium range camera.
I get paid for weddings and portrait shoots once in a while, but mostly i shoot for fun. I do have friends and family help me carry tripods, lenses, and camera bagsIf it is a job, then perhaps having an assistant carrying another camera set-up will work?

not for me. If I'm on a rare trip or vacation and there's a rare shot, i want (not need) a backup card.
What's important to you is not what's important to me. Having photographs of a rare trip with 100% insurance is not important to me enough to have a camera with dual slots.
As an amateur, two card slots in my camera is not important at all. Granted, I don't work all that hard for a shot. Perhaps if you depend upon selling your photos to pay the rent, it may become an issue, or to have jpegs on one and raws on the other - mostly for convenience, it might be useful. I think only once have I totally filled up a card, and as always, I had a spare. Yes, I download and format after each shoot, so it just ain't that big a deal to me. YMMV.
Smart photographers know their own needs. Whether that is one camera with one slot or two with two. I don't know anyone who thinks two card slot cameras shouldn't exist. Or don't see the value. Just not everyone needs two cameras with two card slots for what they do.There is one shoot I do that I do about 150 portraits.

Second card should not add too much cost except different model has different chip. CPU/chip control the slot. Price different just marketing decision.
