If we'd had to wait for governments to take on all of that research and all of the funding, bearing in mind that governments tend to move slowly and bearing in mind that extremely poor governments don't tend to have an extremely large amount of money, we might have been waiting for a really long time.
De haber esperado a que los gobiernos asumieran toda esa investigación y todo el financiamiento, dado que los gobiernos tienden a moverse lentamente y que los gobiernos extremadamente pobres no suelen tener gran cantidad de dinero, podríamos haber esperado un tiempo muy largo.
