#5I won't understand why Cowork isn't simply opt-in. It also installs a ~10GB vm bundle which you cannot remove

#7I've stopped using cc a while ago, because it always comes up with new surprises like that.

#9The weird thing is that this is probably a performance optimization for quick responses when a user asks a question.
My agent harness spins up a VM too, but it spins up on demand, cools down in 10 minutes and warms up when I focus back on the app.
The files it works on actually lives in a mount.
People take more time to type a prompt than the VM takes to spin up on a fast machine and on a slow machine, the cooldown naturally frees RAM back to the machine.

#10The VM itself is for Claude Cowork which does all work within the VM sandbox. That doesn't help answer why they spin it up immediately and don't have a way to disable it though. Just the "why it exists" question.
