Unless your retirement plan is dying you at the very least need nurses to keep you clean, doctors to keep you alive and farmers to keep you fed into your 90s.
If 2/3rds of the population are over 60 none of those jobs can be filled with the number of people to keep even the top 10% alive. At that point soylent green becomes reasonable policy.
Magit is probably the easiest one for casual devs to appreciate.
"M-x magit" get a nice list of the status of the files in the current branch.
After you mark which ones you want to keep by moving up and down pressing s(tage) u(nstage) you just press "c c" and write your commit message. Then you press P and your git repo is up to date.
At a previous job the head engineer flagged the number of commits I was making as an issue since I must be wasting a lot of time pushing incremental changes. When I showed him that it took me about as long to push changes to my branch as it did to save the file he was flabbergasted that one could use git without pain.
You seriously underestimate just how much _not_ having to tune your llm for SF sensibilities benefits performance.
As an example from the last six months: people on tor are producing better than state of the art stable diffusion because they want porn without limitations. I haven't had the time to look at llm's but the degenerates who enjoy that sort of thing have said they can get the Llama2 model to role play their dirty fantasies and then have stable diffusion illustrate said fantasies. It's a brave new world and it's not on the WWW.
