You are thinking of dl.google.com. It was a Go program that replaced a very old single-threaded C++ server (using the ancient SelectServer C++ core, deprecated at that time). The thing you have to realize about Google infrastructure is it does not require vertical scalability of its service backends. It is very typical to write a program and deploy it with 100 replicas having one CPU each on 100 different machines. A variety of load balancers (all written in C++, naturally) papers over the complexity. Nobody at Google expects a Go program to occupy an entire machine because Borg packs hundreds of services onto a single machine. The question is for _you_ do _you_ have Borg or another workload coordinator that allows you to do this? Or do you have "the database machine" and "the server" where you expect individual processes to scale up to many cores?
BTW the reason dl.google.com rewrite was faster was not because it was in Go, it was because the C++ server was serving off its local disk and the rewrite was serving off a cluster file system with ~infinite I/O capabilities. Apples and oranges.
It was even crazier: when the original download server was written, local disk was faster, mainly because the network wasn't too fast (rack locality was a concern, way back when), but also because GFS chunk servers weren't, either. At the time of the rewrite, Firehose and co. were being deployed everywhere, D did a better job at serving bytes and, later, local disk use was placed in a lower QOS level. Unless you were one of the few teams that had a good rationale for dedicated machines, if you fought for I/O time on a given disk against D, invariably you lost.
Healthy Workers is a Amsterdam-based startup that measures thing such as: air quality, CO2 and consented employee data (e.g. their sleep and focus) and makes an analysis what parts of the building have an unconductive work environment and how this can be improved.
Conference rooms with bad air are the first problem they look at.
They are hiring for a head of sales and a product designer: https://healthyworkers.recruitee.com/
That's basically because Larry Page really, really cares about it. He's kinda like your friend with a Kubrick obsession that can't stop bringing up facts:

He was on to something! Jokes aside, I think he just has a heightened sense of smell and that's why he had air filters stronger than law requirements installed everywhere, at least in Mountain View.
