I am sorry, but this looks insane

I am a console user. I really just started to use X11 again about two weeks ago, to sometimes test an a Qt application I am developing. I am not using Firefox or anything similar, all my daily work happens in shells and inside of emacs, in a console, not in X11. BRLTTY runs all the time, translating the screen content to something that my braille display can understand, sent out via USB. So the most important programs to me, are really emacs, and brltty.

This is my desktop, that is up since 179 days.

I am sorry, but this doesn't look right, not at all. I am not even beginning to talk about dbus-daemon and systemd. Why the HECK does packagekitd (which I definitely don't use actively) use up more then two hours of plain CPU time? What did it do, talk to NSA via an asymmetric cipher, or what?! I play music via sshfs, sometimes FLAC files. That barely consumed more CPU time then brltty, which is probably the most active daemon on my system, erm, it should be.

I don't want to chime into any flamewars. I have accepted that we have systemd. But this does not look right! I remember, back in the good old days, emacs and brltty were my top CPU users.
