From the perspective of the 2000 bubble though, that's exactly what people thought. Pre-crash people thought everything needed to go online, post-crash people thought you couldn't succeed unless you were 'clicks and bricks' but really just bricks was better. Now we're looking at some over-valuations in social companies that will probably burst but people won't be reevaluating whether you can really have a business on the internet or not. And yes the 2000 bubble had a big impact on the careers that kids choose.
