Problem is that the type of person that leans towards collaboration and likes to explain things may be getting burned out right now or may be among the first to be replaced.
Anecdata: I am that person, loves explaining things, love seeing my colleagues learn things and grow. Needless to say, I no longer hold a job in the industry.
OTOH, it's great for the type of person like me, who likes answering questions but is rarely asking them. Like, I don't want to interrupt my colleagues for something I can figure out on my own in comparable amount of time/effort. AI is now scaling this to questions previously way too difficult to answer on my own.
