You get full root access on a VM connected to Colab and to the internet.
I worry that evildoers might soon start to create thousands of google accounts and thousands of colab sessions to get free GPU's for crypto mining.
Hopefully google can find a good way to keep abusers out while still keeping it free for those of us who have a more legit use for this stuff.
