Or when a company that's just a website is worth more than chains of actual, physical hotels.

Actually most hotel chains do not own the hotel real estate, they are management companies.

That makes sense if the website can reach and engage many more customers.

Using sensors inside industrial equipment to optimize maintenance schedules and reduce downtime seems among the less-bubbly business ideas to me.

You'd think, wouldn't you? I'm exiting that market post-haste.

They tried setting some some similar innovative type of tech offices during the .com boom. The offices were closed down and GE went back to their corporate roots. My guess is that history will repeat itself.

Ha! When you out it that way, it is very funny, but makes me a bit nervous.
