As Toohey mentioned, views are (almost always) still necessary as a way to programmatically get to data.
In terms of UI, grid-based views (as opposed to Carl's example of discussion features) are only useful to people who want their data to look like a spreadsheet. Spreadsheets are only useful to people who don't have an app that tells them what they really need to know without having to look at ALL the data. Ergo, if your application UI shows them all the data, the app has failed.
