The stone age did not end because the world ran out of stones, and the oil age will not end because we run out of oil. It ended because bronze tools became cheaper.
The origin of that quote attributed to Ahmed Zaki Yamani who was the Minister of Oil for Saudi Arabia in the 70s, is actually difficult to trace back (and the analogy can be critiqued in many ways). But in any case, as experts of any given industry this brings us back to what we love to forget:
We’re not going out of business, because what we are experts in is getting out of fashion by itself (or as a resource, is depleted). We get out of business because “better” comes in. Innovation answers to this simple formula:
Customers x Time
So pause a minute and ask yourself:
What are your stones? What are the bronze tools coming in? And what can you do about it if your salary depends on cutting more stones?
