But Nordstrom is not a tech company. They sell shoes and nice things, that is all. The stores let them provide a luxury experience IRL as well.
A pure ecommerce Nordstrom would need maybe a quarter of the current staff in technology. What is it you propose to do? Like you would need all of these satellite offices and tech dev hubs for a [also useless] company like Facebook. I know, more magic mirrors! That will do it. Make a ... social ... video .. app with shopping ... and... RMS ...
And in the long run it's just a battle of different supply chains, whittling costs down to nothing.
Tech people have been useful, but they are not as important nor as intelligent as they think.
You're clerks.
