I'm not sure if the price in the article is wrong. NAO costs between 5k-15k, but Pepper uses much cheaper hardware and is sold at a loss so it might be possible to buy it for 1.6k.

Like you mentioned, Boston Dynamics and Aldebaran have different goals. If Google however is interested in making a household robot then I think Aldebaran would have been more suitable for them. Pepper and NAO have actually been used in public places like hotels and shops, but would you imagine one of Boston Dynamics robots being used there?
