Can Engineers Overcome the Impending Limitations of Moore's Law?

I say concurrency not parallelism as I don't yet have access to properly parallel hardware ... :)

If you don't have parallel hardware, concurrency is just sequential but with extra overhead. That is, if you have a single-thread process in a single CPU and you make it multi-threaded but still on the single CPU, all you have done is add thread overhead.

Managing multiple downloads + many other use-cases.

"Take this list of URLs and download them all". You don't want to sit there doing nothing while your 1st and only download times out.

Edit: Yes you can implement this single threaded with async and a non-blocking downloader but that's a bit weird - and most libraries implement nonblocking download with threads anyway.

Good point. Thanks. I had not thought about I/O bound processes.
