Diamond thermal paste is already a thing, right?

They could even create the equivalent of a "perfect pixel" guarantee - "perfect lattice" guarantee, the diamond screen is flawless down to the atom or your money back.
That could flip the script on DeBeers in a big way.

Now, that doesn't necessarily mean that a diamond screen would be worse than what exists today but it wouldn't be something invulnerable and resistant to any impact either.
The predecessor to your phone, my Nexus 5, also contains Gorilla Glass 3, and yeah, I don't use a case, I don't use a screen protector, and there are no real scratches on the screen, and it has rode around in my pocket for over 2 years.
Expect to see them on disposable razor blades within a few years (which is probably going to disrupt that market as well..).
Well...not, historically, for diamond. :-) That's changing.
Not being an expert in this field, I would guess that the barriers would lie primarily in tooling up the process to handle kilometers of material at a go, rather than making one-off surgical cornea scalpels.
Now I'm wondering just how many kilometers of razor blades are produced annually. Many, I'm sure.
Now there's another industry that only survives by the grace of marketing and people not bothering to buy a cheaper double-edge alternative.
As well as to buy more a more expensive class of product which may or may not be better--yes. But very few people have to be sold on buying a disposable razor.
That's not the point. The point is that the industry survives by keeping the consumers ignorant.
> and most of those same people see a big advantage in convenience.
I wonder how "these same people" decided that there is "a big advantage in convenience" if they have no point of comparison.
Because looking at the friends I have almost nobody people under forty has ever even tried something other than an expensive disposable blade, or perhaps a fancy electric razor. The only people I know who are the exception to it are hipsters who have since switched to growing big bushy beards. Which brings me to my other point:
> very few people have to be sold on buying a disposable razor.
Yeah, because they don't even know there are alternatives. I don't know about your supermarkets, but the ones I've been to don't even sell safety razors any more. A Mach 2 is cheapest thing for sale, and that's what I started out with. I had to buy my double edge at a barber, and I buy razor blades through the internet.
Regardless, compare the cost of one double-edge razor blade to the cost of one of those fancy N-blade thingies with aloe vera gel strips and whatnot. The price goes from the order of cents to the order of dollars (or euros, in my case).
I have a really hard time believing that the actual cost of making these things is 100 times more expensive too; in fact the shaving industry has been accused of mark-ups around 4,000 percent[0]. Either way, the convenience definitely is definitely not 100 times higher.

The convenience/cost relationship is not linear. Cost of a 500ml bottle of water: $1. Cost of refilling that bottle from the tap: $0.0005. Convenience factor difference: almost definitely not 2000x. Yet people still buy bottled water. Is that a paradox? I don't think so, because people put various values on things like time and mental space occupied which may very well dwarf the absolute cost involved.
No, that's also marketing[0], and by the way, the bottled water industry is incredibly destructive for the environment[1]. Also, I don't see how my argument involved any paradoxes.
You know what "convenience" really means in this context? Taking whatever is available at the very limited selection at the supermarket[2], without putting any more thought or effort into it. But when you think about that, that's creating a demand by simply not offering or mentioning the cheaper, less profitable options (because obviously, supermarkets make more money selling the expensive stuff too).

Vacuum-lift airships (at least on Earth) will remain a dream.
Natural diamonds are not perfect, and manufacturing a large perfect diamond is probably very difficult, but I don't think it can be ruled out as impossible.
Problem 1: induction cooker. so use gas.
Problem 2: the pots may ignire if overheated...
I'd definitely give it a try.
