It's getting so very old - all I want out of a process is code autocomplete, but I have to grant it read & write permission to my entire disk and network. When do we get good permissions and sandboxing and isolation? This can't go on.

I agree granting processes permission to read any file is unsustainable.

In Linux, sandboxing with Firejail or bwrap is quite easy to configure and allows fine-grained permissions.

Also, the new Landlock LSM and LSM-eBPF are quite promising.

I build my own. Maybe I nee to externalize it...
