We don't have the same basic needs. People are running VMs on their laptops so they can test things in an environment similar to production without having to run extra servers for every developer/sysadmin to test with. Back in the 80s you're QA and Production environment were very likely the same!

I'll admit that modern text editors and communication software have grown resource hungry, but a lot of that comes from being able to deliver a strong, cross platform experience. I remember desktop Java doing much of the same with just as bad resource usage. Same with applets.

Sure, but that immediately raises the next question of why those VMs are so big...

Yeah, the fixed cost of a VM context is on the order of kilobytes in the host kernel, megabytes in the guest kernel. And with VM balloon paging a guest VM acts much like a regular process in terms of memory usage. It's not VM usage that hogs memory, it's the applications, regardless of VMs.
