We are bringing up machines in society today. Interactions with society do apparently help them to pick up human values - so cars have air bags, blenders have safety lids, and social networks have privacy awareness.

Attempting to avoid interactions with society means that your machines will be untested, and they will be insulated from economic growth that might fuel their development. So: other things being equal, such approaches are less likely to be safe, and more likely to come last - in which case their safety is irrelevant.
