Actually there are plenty that while technically right, are also technically meaningless because they are right by a wide margin.
Namely, the materials and measuring in nanometers.
First, the materials are by no means impossible.
Curved glass are used extensively in architecture.
Aluminium are used in auto parts, aircraft parts, ladders, etc. a good percentage of those auto and aircraft parts are milled, for their purposes, they are so hard that they don't dent when dropped, so i am pretty sure their aluminium are denser then a phone's
And diamond tipped bits are nothing new, what do you think we used when steel bits could not do the job? Lasers? They are not the most cost effective option for most commercial projects and Lasers are presently confined to cutting 2D shapes from sheets of materials in terms of mass production.
Why did they not mention their curved oled? Thats something that actually is novel!
But the one thing that really caught my attention was that bit about measuring in nanometers. I would like to explain something and then let you know what i think of that. First off, some information.
A nanometer is
1/1,000,000,000 of a meter, or 0.000000001 or a meter.
Most manufacturing industry measures in microns or in terms of micro meters,
Which is 1/1,000,000 of a meter, or 0.000001 of a meter.
Now, thermal expansion,
Going from 20°c to 21°c,
A strip of 10 cm long aluminium strip would grow by about 2.4microns, or 0.0000024 of a meter.
A strip of 10cm long glass, would grow by about
0.9microns, or 0.0000009 of a meter.
What this means is that if you were looking for deviations on the order of nanometers, you are looking for deviations of +/-0.0000000xx of a meter. Coupled with thermal expansion, your results will fluctuate by thousands of nanometers off because you cannot absolutely control temperature(human touch transfer heat for instance). Your measurements are literally functionally useless when viewed at the nanometer scale, you might as well use the micrometer scale.
So all in all with all that considered, i thus would like to state for the record that, That video is full of ********.

Addon:
Here are some objects that measure about 10 micron :
http://en.wikipedia.org/wiki/10_micrometres
Notice at the end paper is just under 100 microns thick,
Blood cells are about 10 microns wide,
This goes further to show,
A) you wont see thermal expansion of 2microns and
B) nanometer precision is nonsensical.
