Herein lies a dangerous assumption prominent in neoliberal thinking: that "building something for people" is only possible by making something that is inherently "profitable." Kay has spoken endlessly on the fact that PARC was -- in spirit, structure, and personnel -- largely the last gasp of the ARPA/IPTO funding culture. That we don't have this kind of basic research funding anymore is one of the reasons we don't have inventions on par with the Internet and personal computing. This is one of the points he harps on about.
Few companies today will create anything that is a truly shattering invention, for the simple fact that companies are not structured to invest the time and money in ways that such inventions demand: decade long cycles, where failure and "wasting" money is the norm. The quarterly earnings cycle prevents this. What's worse, that cycle has been absorbed into the way politicians and governments now think. Today the NSF wants you to demonstrate how your research will produce the desired results when applying for grants. That's not how exploratory basic research works. You'll only ever get more arcane iterations on current systems and technologies.
Kay has spent his life doing this kind of exploratory research. PARC, Squeak, STEPS -- I'd call all of that "execution." But perhaps others who see businesses and profits as the sole reason to get up in the morning would disagree.
