I'll be honest, I live in a bit of a Web bubble. While I dabble in other languages, JavaScript is by far what I spend the majority of my time researching. And through that I've read how because of Spectre and Meltdown certain features in web browsers (Chrome, Firefox, Edge, and Safari) are all disabling SharedArrayBuffers (while allow for sharing memory between threads in a web page) as well as making the readings from performance metrics temporarily less specific.
On top of that, Windows, Linux, and macOS have all worked on OS level patches in the mean time.
So I thought I'd ask about Android or iOS since I've seen ARM is affected too.
