What makes you say that remote development is mandatory? I think it has less to do with "this day and age" and more to do with your current employment.
For me and a lot of people it is. But not because of employment. one big use of remote is to remote into docker containers. why docker containers? I can have a different set of dependencies for each project and yet have my different systems communicate with each other over a network.
but for me, the big issue is I run phoenix framework and the older version I'm running my project on can't run the tests on the arm version of docker os I had to create a x86 machine on hetzner.
