Presumably the Go design team added the speed lines at the left to connote speed, performance, and and the future progress and adoption of the language. But the way the lines are conceived is generic. The variation of lengths, meant to evoke the chaotic air turbulence behind a rapidly accelerating race car, is tired. Nothing we haven't seen millions of times before. And not particularly well thought out. In direct contradiction to the expressive power and beauty of the language itself.
The best thing about the design is of course the hidden encapsulation of the mathematical symbol for "infinity". Although, again I find myself at a loss to understand the exact nature of the relation. A possible reference to the ability to spawn millions of goroutines?
The execution of the infinity symbol itself is muddled by the sharp corners of the G's aperture. Shouldn't it be more rounded? It's menacing resemblance to a PC-era on/off power symbol rotated 90 degrees counter-clockwise is distracting.
And lastly, the most troubling of all. Whither the beloved Gopher? A clear nod to the linux penguin. And a secret totem to those who have been initiated. A hieroglyph for the high priests. No text necessary.
Make no doubt about what this rebranding portends. Enterprise Go, Team Edition coming soon ;)
