I'm a former nmap core developer and even though I no longer actively contribute the project still is very close to my heart. It wasn't "revolutionary" at first, in that port scanning was already a thing, there were multiple available scanners out there. Most of these tools had their own syntax though, and they usually offered one specific type of scan. So nmap came and aggregated everything into a relatively simple tool. It then became incredibly successful and from that popularity nmap got its greatest strengths IMHO : portability, versatility (these crazy options implemented to satisfy super-specific needs) and the OS and service version signatures captured as a collaborative effort over more than a decade!

Thanks Fyodor & team!

The Stanford HPC team reported last year having sent more than 2PB to Google drive using Lustre/HSM. This was using the public API and the fact that gdrive is free for *.edu sites.

I would add "The Formation of the Scientific Mind" by Gaston Bachelard. This text analyses the nature of the mental patterns that prevent from making actual discoveries (what he calls "epistemoligical obstacles").

You don't have to wait for requests to complete, so slow or broken connections don't cause hangs. IIRC, zmap[1] takes this approach. This allows the "probe" stage to be executed essentially as quickly as you can send packets, while you lazy load the results

nmap dev here.

Nmap is already asynchronous, as you described multiple requests are multiplexed (cf select(2), epoll(7), kqueue/kevent depending on your platform...)

The core difference between nmap and zmap is that the latter is stateless. Which allows a much higher throughput, but also prevents from applying some smart detection mechanisms. Thus, both tools are complementary, and no, there is no work being done to make nmap stateless.
