In the meantime, the most intensive efforts to promote and experiment with practical post-capitalist alternatives are coming from those on the left who are intensely focused on technology. Efforts that came out of the Free Culture movement were primary elements of Podemos, and have combined with other social activists to form the Barcelona en Comu party at the municipal level—perhaps the most comprehensive government-backed effort to create a social and solidarity economy that is distinctly different from capitalism as we know it. [...] Harnessing that intensive experimentation and practical utopianism of online communities, and avoiding the twin errors of treating technology as an exogenous force or as strictly dominated by institutional factors is the biggest payoff of the effort to integrate technology and law into the field of political economy. Only if we understand how institutions and ideology shape and interact with the economy, polity, and technology can we develop such a coherent program; and only such a coherent program can be broad and systematic enough to change the course of the economy that neoliberals have built for us in the past forty years.
