"You can sell nothing for a mark-up for a while, but only until something starts eating away at it. Now I can go home and click on Yahoo, call my sister and talk over a microphone for free"

In this quote, Michael K. Powell is highlighting the temporary success of offering a service or product at a greater cost than its original expense. He suggests that this may work for a short amount of time, but ultimately, external elements will start to decrease the earnings. Powell then moves to a more individual example, stating that he can now easily communicate with his sibling free of charge through innovation, highlighting the constant evolution and effect of innovation on our daily lives. Overall, the quote works as a reminder that even the most rewarding ventures are not immune to change which versatility is vital for long-term success.
