I’m guessing Jim Keller Has some great accomplishments under his belt which is strange because he seems quite a confrontational person A lot of ego at work,(reply>), @Stereo review X I understand your point and agree.  A wise person is open minded and able to take in new information, even if they are rigorous in their own thinking.  To assume one is not able to learn from other people is to assume that one knows everything.  I do get a little of the latter from Keller.,(reply>), Loanword Eggcorn no I wouldn’t disagree with what you just said .<br>The bit that I don’t get is .<br>The ego I see the desire to be right or a kind of desire to be dominant .<br>It’s like an inbuilt desire to reject other people’s information which would lower your intake of information.<br> musk does not exhibit this arrogance (not quite the right word),(reply>), Do you think someone who has great accomplishments has achieved that without confronting some old idea or challenging a prior assumption?
