So a seriously limiting concept from mobile/web world is making it into Linux as well? Soon we won't be able to do anything with our computers, but we will be "perfectly safe". Everything I dislike about iOS is now becoming mainstream. Disclaimer - I wrote a book about cryptology including TPM, secure boot loaders, PKI, etc. another one about 3D graphics and am very aware of the issues and trade offs. But sandboxing is a charming but ultimately silly solution that ultimately removes any capability from the hands of users and slows everything down - it already negatively affects graphics performance of browsers (tainted canvas anyone? how long would WebGL shader hack to bypass this work until we are forced to accept 100 pixels/second performance with sandboxing?). There are even rumors that Skylake is going to be slower and more power hungry than Broadwell due to SGX (we will see soon I guess). Is it really worth it?
