Masayoshi Son, the founder of Softbank, has raised a $100 Billion fund to invest in, among other things, the singularity. I'm sure the ultimate plan for Boston Dynamics is to build robotic/cyborg parts that will augment humans. I know this sounds a little out there but Masayoshi Son is a serious visionary and plays the long game - e.g. Softbank's 300 year vision plan.
