I hear your point of view sounding like older people 10 years ago who I heard saying they did not like Smartphones, they are all glass and they break. A very similar argument was had over 100 years ago when Air filled tires were starting to be used over solid rubber tires. People said they would pop and had valid issues.
Well progress is made and mostly everyone has a Smartphone now they are glass and they do break. And everyone has air filled tires and they do pop or get flats.
As such in 10 years everyone will have flexible or foldable phones.
The advantages out weight the drawbacks.
As you can see in the video linked below. The most popular format will likely be a folded iPhone X 5.” style device which can Unfold into an almost 10” display size since its flexible.
So enjoy your Smartphone and your Goodyear air filled tires in less than 10 years you will love your iPhone Pro which foldout into a tablet.
Also here is another Samsung innovation
A unbreakable OLED display that’s bendable and its not a prototype it’s been verified by UL Laboratories so it’s ready for the consumer market.

(P.S. please don’t think of phones as Foldable it’s a marketing strategy Samsung is all too happy to take credit for like LED TVs.
Displays will be “bendable” like a piece of plastic not foldable like a piece of paper.)
