Making money here means net profit. For a growing business, this should be negative. If you can borrow money at a 5% interest rate and use it to grow the business at a rate of 10%, then you report a loss but your company value increases. Amazon's strategy has been along these lines for most of its existence: all gross profits are reinvested in the business, so they always show a loss and their increase in value gives them the access to more capital through loans or by issuing more stock.

This is a common problem with most AI announcements. Is 80% accurate better than a simple statistical model? Often not. Does it scale up from a small sample size? Remember the recent face recognition thing that managed with only a hundred or so pixels? Sounded impressive, until you realise that the training set and the testing set were the same and that they only included around 1,000 faces, so simple information theory tells you that you only need 10 bits of information to identify each one and 800 bits doesn't sound quite so impressive.

And yet, in the UK where it is illegal to make union membership compulsory, unions seem to work better. If people see the unions working on their behalf, then they're generally happy to pay the dues (sure, you get a few freeloaders, but not enough to break the system). If a union is not representing the interests of the majority of its members, then it will quickly see its funding dry up. Importantly, voluntarily paying union dues is a big signal to the employer that the union actually does have negotiating power: it implies that the the union is trusted by the majority of the employees to bargain on their behalf. In many places, you have two or more competing unions (though the law says that any deal reached by one union must be offered to all employees, irrespective of whether they are members of that union) and so not only does a union have to represent its members' interests to retain its income, it has to represent those interests better than the competition.
