Why AI tools failed to catch corona cases ? artificial intelligence, covid 19

Taking many efforts, large number of predictive technical tools like artificial intelligence, Machine Learning were developed. None of them made a major difference & some were found potentially harmful to human body. Few months back, the Turing Institute, It's in UK as a national center for technology, machine learning, data science and artificial intelligence, kept out a report summing up discussions at a series of workshops and seminars it held in late last year ( in 2020). The clear consensus was that artificial intelligence and Machine Learning tools had made little, if any, impact in the fight against corona virus i.e. covid 19. Two major studies that assessed hundreds of predictive tools developed last year.
