Many people purchase Google Fiber for 900Gb/s down b/c they deem the quality of Comcast's 25Gb/s down as unacceptable. Are you making the counter argument that 25Gb/s is optimal given the reality that we're living in a time where 900Gb/s down is attainable except for the lack of shareholder will preventing its deployment? I've built my own modems. I witnessed the stagnation around 2400 baud. I'm unimpressed by your suggestion that commercially-available bandwidth is at an "optimal" speed.
