Let’s say you have just 1 penny to your name. Poor you! But a private benefactor has thrown you a lifeline. He’s giving you two choices.

1. He promises to double your money, so now you have 2 cents! You are not too excited about this.

2. Your other choice is that he will give you a quarter. You are still not too excited.

Furthermore, he will continue to double your pennies every day for 30 days. Or he will give you another quarter every day for 30 days

Which one do you choose? Exponential change with factor of 2 OR Constant rate of change of .25 each day? Who do you think the benefactor is? It better be Elon Musk…
