Attend CppCon once and it totally changes your mind. Mind blowing number of pure educational talks. There is literally no other conference comparable in terms of technical talks. The rest should be renamed to AdCon.
CppCon, BoostCon, MeetingCpp and others all archive their material on YouTube. I’ve spent countless nights falling asleep on the couch listening to fascinating C++ talks :)
same actually, i always tend to listen to them late at night.
