What is up with this cynical comment? They tried to solve the problem and it turned out to be not feasible. Just because they failed doesn't mean trying was bad. I suggest learning about the concept of "expected value".
Compare that for instance with the Horizon 2020 project "RePAIR – Reconstructing the Past: AI and Robotics Meet Cultural Heritag", which ran for almost 5 years, had a budget of only 3.5 million Euros and that money was divided among six(!) different partners.
Maybe that gives a little bit of a perspective on "expected value".
