Natural technologies have incredible constraints. Think about it. If you were an engineer and I told you that you had to build an automobile, but it had to start off to be this big, then it had to grow to be full size and had to work every step along the way.
Las tecnologías naturales tienen increíbles limitaciones, Piénsalo. Si fueras un ingeniero y yo te dijera que tienes que construir un automóvil pero que debes empezar así de pequeñito y luego tiene que crecer a tamaño completo y tiene que funcionar en cada etapa.
