I'd just expect more from someone who takes 30+ minutes to debunk a claim that doesn't matter and most people have never heard to be more particular in getting details correct.
On the first part of the video, to be more constructive, it does not matter why a language or tool or whatever was made. The claim, that he debunks, is that OO languages were made to be good for working with teams. Whether it was made for that is immaterial, and no one needs 30 minutes of mostly historically correct video to get to The Truth(tm) of the matter. What's more interesting, and he never bothered to get into, is whether OO is actually good for working with teams (I can go either way, I've dealt with enough garbage OO programs to know that OO itself does not help things, but enough good OO programs to know that it can help things).
To anyone who has not yet watched the video, the second half is interesting, the first half is mostly a waste of time.
