A lot of the underlying technology for paperspace certainly exists today and its best to think of what we are doing as providing a layer on top of it all (and polishing the pieces that didn't work so great before):

To give an analogy, cloud storage was definitely around long before dropbox and google drive. It was simple, I uploaded a file to FTP, you opened your FTP client, and we could share files. The reality was that less tech-savvy people might never get past the install step.

What dropbox/google drive/box did was take an existing (and increasingly commodity) offering and wrapped it in a layer that made it accessible to a whole new class of users.

Digital Ocean is amazing and we are shooting for the same simplicity for full desktop computers.
