Depends. Do you want the possibility of an AI model being able to fork over some private details in your convos? The potential for someone that doesn’t like what you believe in to subpoena google for this data?

As for bricking, it won’t, and the whole process is on the website, using a chrome-based browser and usb cable (it detects which pixel you have and does all the hard stuff) but you do have to back up your stuff as it will erase when it gets graphened.
