Hypervisors Memes

The existential crisis hits hard when junior devs finally grasp that their precious code is just a tiny speck in an endless Russian doll of virtualization. Their Java app isn't running on a "computer" – it's running on a Java Virtual Machine, which is running on a VM, which is running on a hypervisor, which is part of a Virtual Private Cloud... which is probably running in some AWS data center that might not even physically exist for all we know. Seven years into my career and I'm still not convinced my code isn't just running in a simulation inside another developer's fever dream. The turtles really do go all the way down.
