I had a hard drive fail today, my system went into a drive checking loop, stuck at 64% at boot this morning. It happened to be the HD with all my photographs, 8 years worth of work.
Fortunately, I had everything backed up into the cloud with Dropbox. After installing a new Western Digital Black 4Tb drive, I let Dropbox do its thing, and am now about 50% restored. By the morning, everything will be in the correct place, and I can get back to work again.

Benjamin Franklin was right, an ounce of prevention is worth a pound of cure.

Pardon my ignorance here and someone please correct me if my thought is incorrect as I am still new to digital photography (as I probably need to retire first.) I always thought the jpg from a camera was the result of a quick, internal jpg conversion from the RAW based on 1) user selected options if the camera offers them, and 2) the engineers' attempt to build best guess parameters into the firmware driving the internal computer. Alternatively, true PP is putting the conversion process into the hands of the user and whatever tools the processing software offers. So there is nothing inherently better about PP unless the photographer can do a better job than what the engineers and camera are able to do for a given exposure. PP offers much more flexibility, of course, but whether it is always better depends on whether the photographer has the time, equipment, and skills to improve on the freebie conversion done in the camera and the team behind it. I imagine most any professional, with rare exceptions depending on the genre, would be well enough equipped and skilled, and would want to improve over his camera's jpgs, whereas in my case, and probably those of a few others, I try to shoot in a way that the camera will process them well enough for my humble needs. It boils down to the meaning of "good". It has too many facets to suit a simple generalization. But I believe the point of the post is best answered in saying there is no way a single automated jpg conversion can stand up to what even a moderately skilled photographer can do with even a modest computer and common PP software for the vast majority of photos, though in some cases the camera could come close if it got lucky.
