How much value does this conference provide? Would you attend it on your own dime? I see many presenters going from one C++ conference to another to give essentially the same talk. Specifically, I looked though the talks of the CppCon 2021 several months ago (as most of the presentations became available online) and found very few with a new material. It wasn't enough for me to consider paying upwards of $2K for them. At this point the only reason I'd consider attending such conference is to make professional connections.
