DSLRs, including mirrorless ones, will become rarer and more specialized as consumers use their smartphones for all photography and filming needs. Having a separate device for photography, like a DSLR, will feel like owning vinyl.

Regular large TVs will be replaced by VR glasses more and more for everyday media consumption. It will be like putting on sunglasses. I'm guessing large TVs will combine computer monitor capabilities as we move towards this.

Subway or bus cards will disappear, replaced by phones or touchless entries.

Buying large desktop PCs for gaming or others will disappear instead of laptops (maybe). I feel like the way is like an online hosted gaming platform like Stadia (though I know it didn't pan out).

I would say the camera market has pretty much stabilized by now. I don't think phones have much more to offer compared to a modern camera. Using a real camera is way more enjoyable and creates a better or same image as iPhone.
