Pero antes de eso, manejar el código asíncrono era mucho más complejo y difícil.

En versiones previas de Python, podrías haber usado hilos o [Gevent](https://www.gevent.org/). Pero el código es mucho más complejo de entender, depurar y razonar.

En versiones previas de NodeJS / JavaScript en el Navegador, habrías usado "callbacks". Lo que lleva al "callback hell".
