It can definitely handle virtual workspaces and global state (if I'm understanding what you mean). I have an Aerospace-like implementation here: https://github.com/mybuddymichael/Helm.spoon
It has several features from Aerospace, but Hammerspoon's window management performance is not nearly as good as Aerospace's (not surprising!).
Overall, I've found it easier to just fork Aerospace and add various extra features to it, so that's what I'm doing now.
I've been using Jujutsu (https://docs.jj-vcs.dev/latest/) exclusively for many months, but I've always been intrigued by what GitButler is doing on top of git.
Duolingo has been around for so long that I feel like there should be a wealth of case studies showing how folks have used it to actually learn new languages. I've yet to see one, personally. (But perhaps I'm not looking hard enough!)
I actually think jujutsu is _more_ ideal for the agentic era. It makes it so easy to explore directions, experiment, play, backtrack, move commits around, etc.
I've been using Macs since Mac OS 9, and Snow Leopard was indeed very good. It remains my favorite version of Mac OS. I actually think it was Snow Leopard that started the rush of developers to Mac as _the_ platform to use.
I've been a happy HHKB user for almost 10 years and a Vim user slightly longer, and this is exactly what I do (though ctrl is already in the right place on the HHKB). I believe it was one of the first things I figured out in Vim, because it was so annoying to me to have to go all the way up to the escape key all the time. Ctrl+[ is such a pleasant little chord to hit.
I currently use an HHKB (for almost 10 years now) and I love it. But RSI has pushed me towards building my own split ergonomic ortho keyboard. What switches are you currently using on your daily driver mech? I got some 67g Zilents that I'm hoping give me a fairly close feel to my Topres when lubricated.
This is sure going to make YouTube a whole lot less useful for gathering information about a subject. I can't tell you how many DIY home improvement and exercise form demonstration videos I've been protected from because a lot of dislikes pointed me to the fact that something is terribly amiss in the content. Who knows how much money those ratios have saved me over the years.
I love both Starting Strength and Stronglifts and I think exercise is absolutely critical for everyone, especially knowledge workers. I lift daily, but I still get RSI. Maybe I'm an anomaly, but I think you might be painting too broad a brush with this prescription.
What specific challenges are you running into that make it feel like a chore?
