I wonder if Microsoft's Bing/Edge/ChatGPT integration will go any better than its attempt to marry NTFS and SQL Server (i.e. WinFS)? Spoiler: that didn't go as planned!
Microsoft never really revealed the 'real reasons' why it was canceled; so most people are left to speculate. My personal take is they decided it would become a tech-support nightmare to talk regular users through fixing a problem if the underlying database had an issue.
