In my 33 year SQL Server career, every time I've heard vendor claims like "intelligent" or "self-tuning", it's led to more technically intensive and deeper work. Such technologies deal with lower hanging fruit, and add complexity to resolving problems they can't fix. So bring it on!

Is there any way we can get these info like server/program/user/session id for historical queries with the help of query store or DMV's?
I know dmv's store session info for currently fired queries but not getting from where we can get session info for historical data.
