I’ve been migrating to sync from Dropbox after hearing too many reports of Dropbox scanning user content for things they deem objectionable. I like the end to end encryption, but I have found the mobile experience on iOS to be lacking. It seems to have trouble integrating with Files and uploading files directly via the iOS share menu. Annoying but not a dealbreaker.
As with any technological advancement , there are risks, but if humanity is ever intending to become a spacefairing species, we will have to make peace with nuclear energy. It’s the only technology that comes anywhere close to making interplanetary travel feasible at large scale.
