My concerns about it is that too many people seem to imagine that because historically an outcome had a cause, that therefore that cause must have been necessary, and that therefore the outcome could never have happened without that specific cause. If they Fluyt, a type of Dutch cargo ship had not been invented, would we really have never developed plastics? So the series provides a very valuable insight into historical processes, but some people seem to take that to implausible extremes. A case in point is the many examples of technologies being independently developed by different people under very different circumstances.
