Bullshit. Just from a document editing perspective, going back to a network share where only one person can edit a doc is not going to fly. I used to have to deal with this as IT/desktop support and it fucking sucked. Docs in the cloud give you better collab capabilities and remove the need to have fancy networking, VPNs, international security exclusion groups etc, domain controller bullshit, connecting all of the companies offices together. Connect to the Internet, and all your stuff is there no matter where you are. It sounds like you've never had to support the infra for office workers before. This is way better than it used to be. For a small company, sure, do whatever. But the bigger it gets, the harder all that shit becomes and requires a lot of work to keep it running.
