So, nothing _really_ jumped out, though there were weak clues/hints. I am not a coder, so it isn't obvious to me that a mention of a technology being "8 months down the road" is unreasonable. But now it would be.

Language (and, it appears, also a culture) barrier with management is... tricky since we don't want to come off as racist/*-ist.
