I would take this article with a huge grain of salt. Amazon doesn't give two shits about blind or deaf or gay programmers. This is a nice fluff piece. The programmers there are under absolute stress and high-stakes programming. I doubt that this one story about one nice programmer can be generalized to Amazon. I would bet if you are a blind programmer you would have a much harder time even getting past the interview loop given how biased the whole company is with their Ayn Rand-ish tactics that would obviously not give two shits about diversity or disability.
I worked with one person at Amazon who had a significant physical disability. I can't speak for him, but he is highly valued by the organization because of the quality of his work.
Uber and Lyft have not been the best actors, but someone was going to step in and profit off of public transit's incompetence here.
Even prior to the prevalence of rideshares, Boston was dealing with absurd corruption in attempting to expand on the public transit systems. See: Green Line Extension project
I just hate Uber Pool and Lyft Line - the routes they take are often side streets with lots of congestion and turns, there's a lot of frustration when you're almost to your destination or to a major road and then the driver turns around to pick up another passenger. Drivers often play music I find annoying.
