Unfortunately, many companies do it the other way around. Getting it wrong can spell disaster. When Christmas rolled around last year, people who ordered their kids' presents on-line didn't receive them in time. Then, in August, the e-tailer went a step further. You can't accept that things will evolve for the good randomly or by themselves.
Cultural differences do exist and have to be managed.
Failure to manage the differences could suffocate a dotcom. For one thing, senior managers at dotcoms tend to work closely with other department heads. Yet in an e-business, you have diverse people collaborating on projects. It takes a different kind of person, a different kind of competency. If senior executives at traditional companies need proof of this, one trip to Silicon Valley should suffice.
