Applied knowledge is power.

Doug Latimer got it wrong.

If knowledge were truly power, then the smartest people would conceivably be the richest and most successful.

But that's not true.

Knowledge is just that - knowledge. By itself it's potential power. It's just information; data in a database. When not used wisely, it remains just that. It's similar w/money. Unspent, it's just colored paper and metal coins.

It's when you apply that knowledge to achieve something useful; it's when you spend that money on something valuable and you bring it to reality - that's power because it places you in a position of advantage relative to others. Now of course, maintaining power depends on how well you continue to utilize either the knowledge you have, or learn and understand and implement new knowledge.
