Thirty years ago, if you told me that company that makes casserole dishes was going to be a tech giant, I would have said, you're crazy.

Thirty years ago Corning was already making most of its money from fiber optics and LCD glass.

Pebbles are the phone screens kryptonite.

I feel we pretty much hit a plateau with glass screens on phones, if we make them any harder they just shatter, if we make them softer they scratch.

The only thing I'm seeing is making it way harder (eg. sapphire glass hard) but I'm not sure if that's feasible for phones.

Gorilla Glass Victus 2 has a hardness of around 670 HV 0.2 while sapphire glass is around 2000 HV.

Not a glass expert though, I mostly deal with steel.

IIUC, the point of ceramic glass is that there are islands of hard bits separated by more flexible bits. The hard bits are still close enough together to make scratching difficult. The more flexible bits in between allow flexing under impact.

Sure it is. As the original poster stated, walls in old houses were commonly covered in Plaster Portland Cement, aka "stucco". It's still widely used in construction, mostly for external walls.

Stucco isn’t plaster

I knew a guy who dropped his phone and the battery skittered off beneath some shelving, never to be seen again. I had a Samsung flip phone where the battery cover would fall off at the slightest touch after a couple of years. In my work experience, battery contacts are a source of unreliability.

Good riddance.

The last phone I had where I owned an extra battery or replaced the battery was a StarTac. And there were a variety between that and my first iPhone that still had replaceable batteries. Even when I had Blackberries, I used an external battery pack instead of buying an extra internal battery, because the external could also charge my iPod. Today, if I had a phone with a replaceable battery, I would probably still go with an external battery because it could also charge my earbuds.

I'm not saying no one should want a replaceable battery. I am saying that it would not provide any value for me.
