New Vesus Old Money
The pivotal moment for the entire movie apart from Tom's speech at the electronic convention was his brief negotiations with those purchasing Landshark at the end. His "matter of fact" statements to his brother in the middle of the film, regarding his behavior fueling the fire for promoting investment and stock stability, came off as a confession after this meeting. David Bowie's character was to be the embodiment of established wealth surviving multiple generations. His disgust perhaps came at the awareness he had for the techniques the Tom's had to imploy to maintain their new-age wealth. A classy snob that could not have been pulled off better than with David Bowie's articulate and savvy persona.
It occurred to me that in fact the movie portrays Josh's character Tom as the bad guy in and of it's entire. Unfortunately, the "rockstars" of the start-ups were nothing of the such. They fed into the model of wall steet to garner stock appeal. Instead of allocating funds for advertisement they purchased and ated to their hearts fancy as posters themselves. Hardly villians. This movie could have done a lot more with itself.
