Ah, the fun (irony here). Before user-end computing can regain a semblance of sensibility we will need to move towards guaranteed secure sandbox environments for apps that allow historical re-use of earlier versions.<p>What is happening at the moment is that IMMENSE quantities of skill development and time is continually flushed away everytime Google&#x2F;Microsoft&#x2F;Take-your-pick-software-company decides to retire or dramatically rewrite an app. The situation is even wilder in the closed gardens (Android&#x2F;IOS) and cloud&#x2F;web-only where perfectly fine software disappears overnight and then.. that&#x27;s it. Wake up, we&#x27;re throwing our mental resources down the drain on a completely unprecedented scale because no systemic solution to this issue exists!!
