Where I live, it is already common practice for real estate 'agents' to photoshop the properties listed for sale to make them look fully renovated and furnished. When in reality the house is empty and in very bad shape.
This tech will make it even harder to judge a property without actually viewing it in real life.
I think we can no longer stop tech like this from being used in ads (because that's effectively what property listings are nowadays). The only solution I think is policies/laws that prevent real-estate marketplaces from showing fake pictures.
That all said, I think the author can make big money from realtors by selling this tech as a subscription model.
