Ask HN: Are you still working with a website that requires Internet Explorer?

I ran across one of these warnings the other day while working with a government website, "For best results, we suggest using Internet Explorer".

That warning was so common during the 2000's. Nowadays, it is like cat nip to me when I run across one. Does anybody still need to interact with one of these types of websites? Are you able to interact directly with it or do you need to utilize a virtual machine? I'm so curious.
