I can't imagine getting rid of files and going all cloud in my creative visual art projects - just one second of a 14-bit RAW YUV 4:4:4 5k movie takes gigabytes, even the latest M.2 PCIe SSDs have trouble playing it back realtime, not mentioning "slow" 1Gbit Internet connection at best, though definitely not for upload. I have a feeling we are getting backwards from the efficiency point of view and am thinking this won't be a sustainable way forward - even in distributed/parallel algorithms you try to keep locality to improve performance and save resources, not to transfer everything back and forth via some middle man just because some business guy came up with some "genial" idea how to milk money. Internet companies have a few chances to earn money, subscription being one of them, but massive push into useless cloud for their particular business cases like in the case of Adobe CC or Microsoft Office just leaves bad aftertaste. Also, Dropbox/GDrive don't allow incremental update API calls for 3rd party apps, which wastes precious upload bandwidth, and in addition end to end encryption fully controlled by user is not provided which would justify full uploads. All of this just screams of artificial constraints which do not benefit anyone, in the long term not even to those companies.
