speaking of the power profiles daemon you do have to "manually" change which power profile you want to use, i personally much prefer something more automatic  since i do not like to be thinking about what "profile" i want as i usually want my laptop to respond to
A) power source state, ie: is it running on battery or the AC adapter is connected.
B) the load on the system, the more cpu demanding some task is the higher performance options i want.

for that matter i considered rolling an initscript to use https://github.com/AdnanHodzic/auto-cpufreq but after reading the code it does additional stuff that i don't need and is running on a python interpreter which is not lightweight to say... so i ended up rolling out my own solution which is a very lightweight shellscript that only makes use of very few utilities not to mention can react to the usage of the gamemoderun tool which i use for prioritizing games over other processes when gaming, finally my solution does set some of kernel tunables wihch auto-cpufreq doesn't even touch (tho TLP does set some from what i've seen).
you can grab the latest release tarball from the releases section https://github.com/eylles/afreq.sh and install with a simple sudo make install install-sysv , the daemon is highly configurable tho i have not made a manpage yet, neither does it support pstates for intel or amd tho it is on my list to implement support for those.

Surely that is sarcasm and not a serious question . . .

In point of fact, it's going on and is an epidemic, I have seen multiple instances of people with IT/software/coding jobs bragging online about how they don't really have to work anymore, they get chatgpt or others to spit out the code for them, they check functionality and for bugs real quick, then commit. And get paid a lot of money for doing it.

Can chatgpt or elon's grok write me one?

Hmmm...an artificially intelligent machine, writing code for other machines...pretty sure i've seen this movie.

Spoiler: It doesn't end well.

On Gentoo we have an (openrc) init script to start PPD explicitly at boot, but Devuan appears to be doing the usual "just pull from Debian & don't bother to check it works properly" thing Devuan does, so the package only contains a systemd .service definition.
If you want it to work, you'll probably have to write a sysv init script for it yourself or come up with some other way to start it on demand.

As for TLP, TLP does far more than PPD, but it's more work to set up and isn't (currently) integrated into the major (GNOME, KDE) DEs.
It works fine for my needs on the one ancient laptop I have ever bothered to own though, same as it always has.
