What Does the T2 Chip Mean for Mac Usage?

I just ran into my first set of issues with the T2 chip and after a trip to the local Apple Store came away a bit dismayed at their lack of support for my problem making Bootable Backups. As I read through these comments, I took note of one critical issue which wasn’t discussed. It has to do with the fact that until the T2 chip came on the scene, because the Mac can be booted from an external drive, it is the only computer on the market that gives users a shot at dealing with Ransomware, which has attacked six student’s computers at McGill University, here in Montreal, Quebec. Canada. The Macs that had Bootable Backups simple booted up on their external drives, erased the internal and CCC’d the cleaned up drive back to life.

Any thoughts?
