>> it stopped doing proper research in the field—partly because it just wasn’t immediately relevant to AT&T’s business

It feels like businesses today are better at pivoting. Imagine improving the state of the art by 10X and simply shelving it.

I went looking for a recent estimate of the number of transistors that have been manufactured. It appears to be in the range of 10^23. I'm pretty sure there in nothing else anyone has invented that has been replicated in such volume.

If transistors would not be possible, then lots of other stuff would not exist, like solar panels or digital cameras. Handy electricity conversion, etc. I think alternativly we would have miniaturized vacuum tubes much more, the ones that powered computers before transistors (and made them huge) https://en.m.wikipedia.org/wiki/Vacuum-tube_computer

Surprising to me - size reduced vacuum tubes happened and it's still being worked on in as I understand it. There are some quite miniature working vacuum tubes - if you search you'll find more information.

They have the big advantage, that they are not sensitive to radiation, like transistors are.

Wow, nearly a mole. I remember thinking that a mole of any "thing" was impossible.

1/6th of the way to Avocado's Number. ;)

Letters?

Paperclips?

An average paper clip is 204.8mm^3. 10^23 of those would be 2.048x10^19 L in volume[1]. That would be only two orders of magnitude less than total volume of oceans 1.33x10^21 L [2]. So I think not.

I'll be the first to admit this is a meaningless debate but seems fun! I'll say no We don't colloquial think of a HDD bit as a manufactured unit on magnetic disks. It doesn't have a direct macro connection/object. For SSDs the macro analog of a bit storage is a register and those are like 6 nand gates which those are made of like 3 transistors? Exact numbers are wrong I'm sure. It's been a long time.

I'm not so sure. Last time I followed the field, modern HDDs were nanostructured, such that each magnetic domain was literally a physically distinguishable object, in a sense. I'm not sure if that's still the case, and I'm also not 100% sure that ever made it in to production, but I'm pretty sure it did.

At least as of the last time I read the domains were a pretty uncontrolled result of the crystalization and each bit is covering a few statistically. Nanopatterning of the sort your describing would let you make the bits smaller and hence weaker by ensuring a separation and friendlier magnetic environment.

I was thinking the same! Something bio, that has the benefit of exponential growth

Interesting. Do you have a source? How does it compare to other tech, like nails? Or cups? Shoes?

Be careful with large numbers: 10^23 shoes would be roughly 854B shoes for every (~117B) human that have ever lived, that is about 14 million pairs of shoes per individual and per day. I am pretty sure there has never been a market for that many shoes.

Truly the shoe event horizon. Next step: become birds.
