As part of that presentation I demonstrated a replacement build tool that I had been developing, gb.
From the feedback I received after the meetup it was clear that many people understood and agreed with my reasoning why reproducible builds in Go are a problem today. However it was equally clear that I had not done a good enough job of explaining how gb works, and why I felt it was necessary to create an alternative build tool to solve the problem of reproducible builds.
With the help of the go-pm mailing list and the feedback from a group of early adopters of gb, I have put together a website for gb with expanded documentation and examples.
I invite you all to visit getgb.io to learn more about gb.
