My primary responsibilities as a manager are coaching, mentoring, hiring, firing, and solving impedance mismatches with other teams. None of that is aided by technology.
You telling us the advent of video and animated media, along with the increasing ease of making them and sharing them, has not helped? When many thus far have applauded the existence and presentation of information in such media?
That's just one example.
I have trouble parsing your sentence, but i am pretty sure the answer is no, that does not help.
Does your manager communicate to you with youtube videos? No. I have not found that video and animation content creation tools have made my job as a manager more efficient.
Maybe you need coaching not your direct reports. Training can be completely automated via technology with close feedback loops , AI and other techniques. Hiring can also be automated to a large extent specially for technical loops. Objective evaluation of someone’s performance can be done by tracking and task allocation systems. All these can be automated to a large extent.
