The Spectre attack has two flavors. The most dangerous flavor of Spectre uses branch misprediction and cache side effects to read any byte in current process virtual memory. It works on a variety of processors, including mobile phones, tables, etc.
So, why can't we just read any byte in current process, without any Spectre? Why Spectre is dangerous? There are variety of languages which create sandboxes (JavaScript) or virtual machines (Java) to isolate local machine from potentially dangerous code you downloaded from Internet.
