Glad you liked it! As this is a concept, I didn’t flesh that one out. But yes, Upthere is based on the idea that “the cloud is the truth”. It’ll be a long time before a model like that is the default. In terms of security, I’m not entirely qualified to provide an answer for that, but I’ve been reading that Apple is working on it’s own secure cloud services, so we can hope. Expecially because while files on the Mac aren’t necessarily stored on the cloud, a lot of personal data is.
