Most of the people that have been saying this for years have no idea how hospitals or health care in general functions. This includes the internal politics of a hospital, politics of the health care system as a whole and patterns of medical care/practice. As a surgeon, I can assure you that Radiology is not going anywhere. If anything, ML/DL will augment and improve radiology outcomes by assisting radiologists but there is no way as of yet where any type of AI can perform the role of a radiologist- that is, take a radiologic study, correlate that with an often past medical/surgical history of a patient and provide valuable insight into what's going on with the patient. I'm not a pessimist about this at all. ML/DL will absolutely improve outcomes if implemented properly; however, radiologists are going to be augmented, not replaced. They are after all physicians.
Dropbox continues to become bloated but it’s still the only client that supports delta sync across platforms. I tried switching to onedrive and google drive but they all are lacking in sync capability.
Ive watched the first two episodes of fast ai and one thing i can say is that the whole approach of this course is the opposite of what the courses you listed are structured like. Fast Ai jumps right into "how to use the script/tools" while slowly teaching the concepts behind why they work in comparison to the typical ML/AI course that involves complex learning calculus and statistics before doing anything practical.
