from the article :

Just a few humans were present to deal with a handful of tasks -- two to feed bare motherboards to the line, and two to package the finished consoles.

It’s ambiguously worded (up to vs up to and including), but the article actually specifically describes humans packaging the final product: “Just a few humans were present to deal with a handful of tasks -- two to feed bare motherboards to the line, and two to package the finished consoles.“
