The interesting thing about that abstract isn't the 100GHz - all sorts
of handmade graphene transistors seem to be able to do that well - but
the phrase "Transistors were fabricated on epitaxial graphene
synthesized on the silicon face of a silicon carbide wafer" which
suggests that these particular transistors might be susceptible to
mass-production, which is what we have all been waiting for.

One day after the first 100GHz CPU hits stores, all the software dorks
of the planet will invent such abstract, surreal and wasteful new ways
to "program" that you won't be able to tell that CPU from a 1GHz PIII.
Picture a 1TB mouse driver that needs a few dozen virtual machines ...
Because you can.

But we as users are often not much better than bloatware programmers. I
often receive drawings as printable docs. Typically a huge file, even
one-sheeters often wouldn't have fit onto a floppy disk back in the old
days. Yet one can create the same sort of info in a 50k PNG file ...
In 1989 my whole biz book-keeping database set fit onto one 1.44MB disk,
including the SW to run it. My 2009 set would still fit on such a disk,
except that the "modern" SW version needs several times more program
storage space than my whole hard drive had back then.

Does it at least work better?
No it works the same. It's very simple, MS-Works database. I bought the
first version when it came out, 1.05, and it had literally no bugs. The
later versions have way too much fluff for my taste and after 6.0 bugs
crept it. So I wouldn't recommend anything higher. Nothing
earth-shattering, but if copy-paste via keyboard shortcut misses every
so often that does get old. Especially when doing the year-end job.

Then what on earth are you talking about? And why isn't the 100GHz
figure - which you chose to emphasise by using it to name of this
thread - a useful indicator of the speed of the part?

What would be more interesting is how the various crystalline faces

What exactly does cut off frequency mean for a FET ?
In bipolars the current gain drops below 1 at fT but you still can get
some usable power gain in common base configuration at higher
frequencies.
Before the invention of real microwave tubes (such as klystrons,
magnetrons TWTs etc.) much of the UHF/microwave amplification was done
my grounded grid tubes.

Yes, but apart from power gain, say linear applications,
an area where this would have applications is in switching circuits.
Think 100 GHz up to 5 THz (if my info is right) processors.
That would change a few thing.

Because scaling it downwards and otherwise tweaking it will likely push
it to 1THz, which is what the project is aiming at.

There is a company I deal with (I informally administer the computers
for them). Someone there designed a new format for quotations. Basically
a single-page Excel file with some thumbnails of the products. Thanks to
the wonders of MS Office (and ignorance) the document ended up
~200MB. For each quote. They were generating a few GB per day for
something that could have been typed up on a few pages of A4. I only
found out when "the internet got slow"... Then there's another guy there
who likes to regularly dump 5GB of solidworks modelling data onto the
server.

Same here, for a couple of years after we started all my PCB design
files & source code went on one floppy.
