And it's shit.
A Google Sheets is not Microsoft Excel. Data stored in some proprietary databases are not files. A browser is (still) not an ergonomic platform for work.

Exactly. Yes, but really, no. Same for editing images, or doing actual work with documents and spreadsheets.
The problem of the cloud is that data is held captive by SaaS companies, while all we've got are shiny toys working over web browser. We can't exchange data beyond what SaaS vendors allow. We can't edit data in non-vendor-sanctioned tools. We can't work off-line.
We need something that lets you retain ownership and control of your data, supports powerful software running locally, and generally doesn't treat Internet access as if it was electricity (i.e. assumes it's always available).
