There is no question what you say is true for me as well. As much as it is possible to turn off the auto focus and other auto stuff on a contemporary cameras… it just seems impossible to do it… at least for me. Forcing myself to think about depth of field made me control it. On the other hand the Leica does excel at some things that make it unique.
I was lucky enough to travel internationally nearly half time for many years. No matter how tired I was I would go out and do photography most every evening. I shot a Fiji X-pro or Nikon D800 (or predecessor). Under those circumstances the automation (fast changing street photography / low light) automation helped. But with time, forced manual use was of great value.
