OK, but then that’s not really what I wanted to say (and perhaps I really should have avoided the word “value”). Sure, those companies are the most valuable at the moment in terms of profits, but they are subject to the whims of customer tastes, which do tend to change every 10 years or so, and so they could eventually fall. A company that is in the business of manufacturing computer hardware, however, is far less affected by changes in consumer tastes because they could just make any computer according to the form factor of the decade, and could last much longer than the companies that use its outputs as raw materials or components.

So then if a company’s products or services lasts over generations, isn’t that actually more useful than another company’s products which people only throw away after some time? If the longevity of production of a product or service is not proof of the universality of a need, what is?
