So by "the end of software" Peter Wang is saying that we'd essentially have AI or Machine Learning making decisions about complex input. I think it's melodramatic to call that "the end of software". It's more software growing to such a complex point that humans can no longer properly understand or describe what is happening within it (the electronic marketplaces discussed in the clip) or they don't necessarily have control over the software's actions (the killer drones mentioned in the clip). That's a huge problem and I think Peter Wang has good points about it, but it has more to do with oversight of systems and it is not a foregone conclusion that humanity has to build society in that direction.
