They will study the demise of companies like Oracle and IBM. Started out with great leadership and vision. Then they let the financial wizards, sales, and marketing folks takeover. They got away from delivering great products and caring about their customers and employees. The goal of the company was to only enrich themselves. Then they became like Sears and KMart and eventually go bankrupt while new players innovate and take over.
If you don't learn from history you are doomed to repeat it.
