Marissa Mayer, while at Google, kept using dialup at home so she would experience what someone without broadband sees.
How'd she go from that to messing up Yahoo?
Another way to put it is how she became CEO of Yahoo at age 37.
I think one can definitely progress to becoming CEO of a large company by 37 if they make a lot of right moves, which I'm guessing she did. But yeah, to go from being the kind of manager that walks the aisles to the kind that regressed a bunch of great products - it seems like something broke along the way.
I have a 2011 mac mini I'm using as home server. It had Linux Mint for a time (this year) and it was snappy, except for browsing the web. Everything else work fine, even LibreOffice and playing videos. But load youtube and you can see the stuttering.
