You could also ask the guy with fourteen kids how he anneals or hardens certain items, so you could like 'do that too' and take food off his table. That's sixties archeology, everyone's a bro.
Others, like Gordon Childe, tried to be a little more realistic initially and concede that some population movement is necessary and imagine Beakers solely as traveling smiths who do good needs for the unbathed country souls who are happy for their skills, there, in the remote and cloudy island that no one has ever heard of off the coast of Northern Britain.
A guy standing on a island with a bone in his nose sees and airplane flying overhead and being inspired, immediately begins processing bauxite and tapping rubber trees. These arguments are repeated with regards to many of the technological changes in the third millennium, lithic production, pottery, whatever. It kind of reminds me of this. Funny.
