I think this is a great effort and I applaud their efforts. There are also a lot of very good points made in all the comments below, summary: 1. Simply changing the frequency of the voice does not necessarily mask gender, other intonations

This is a fantastic idea, I would expect no less from YC. A couple of thoughts I have off the top of my head: 1. Design with hyper-loop in mind from day one. 2. Easy access right of way for utilities, most cities bury everything which is si

What about Gilfoyle ? He is my favorite, I guess because I am an engineer and also I guess a NBA (Natural Born Asshole) so I can relate. Maybe he is just your typical NBA Engineer ? Not any particular well known person.

This topic is very interesting to me from a little different perspective. I am a senior member of technical staff at a very large company and often managers will have me sit in on job interviews with candidates to cover the technical side.
