Software shows infinite expansibility - a single piece of software can be run everywhere simultaneously, without it being any less useful to any single user. This is also the case for a piece of knowledge, and video entertainment, name branding, data warehouse packets. The same dynamic works for a piece of knowledge. Me-too imitators that follow, even if they acquire an attractive appearance, are not the principal contributors to social welfare. Superstar rewards, where one or a few own the whole market, can be optimal for society's welfare.
Computer software is differentiably knowable.
Outside its originator, users need to expend effort to make the software really useful. Similarly, with knowledge, and other sophisticated goods produced in the modern weightless economy. The demand side in the economy therefore becomes critical. It is not just a matter of building up technology on the supply side. The same applies with the knowledge industry and its practitioners.
