The only labor-saving advantage to these sorts of machines comes from them using other people's labor: my own work is not going to help me produce more work. And other people might know better than me about something, but not being able to trace the source of any output makes it impossible to analyze the chain of reasoning that led to it. It doesn't have use either as a creative tool, as a research assistant, nor as a mechanical part. Its almost a toy, except it steals everything you give to it.
