A Place for Programmers

Is there any place online where one can discuss deep technical aspects and questions? Most if the stuff I need to discuss with anyone is either complex or relatively deep. It’s always been an issue. But today most sites I used over the years have become awful (stackoverflow) or too shallow (hn). If there is a place for like minded people, then please invite me in. In a community of people that eager to learn there will always be added value for everybody. IMHO
