Not bad article, but intro deeply confuses the issue. If you want fast builds for your org, use a build server farm that is much faster than the fastest workstation, and sma incremental builds locally or on your cloud desktop.
A local UX machine (15" Mac not built in the Dark Ages of 2016-2020, + desk monitor, good for 5+ years) with a FUSE mounted remote storage and a build farm is a great combo.
I used to think so, but I have yet to own a Mac that survived more than 3 years. However, that may have been partially due to the "Dark Ages", but more like 2014-2021.
I'm happier with something Linux friendly (thinkpad x220, pinebook pro, etc) and a remote system I use over ssh (sshfs, ssh+vim+tmux, etc). All at the great cost of ~$220 + $5/month?
