The time has come to challenge the predominant controlling paradigm of the World Wide Web. We need to replace controlling “SEAMs” with empowering “HAACS.” Over the past two decades, Web platform ecosystems have been employing the SEAMs paradigm – Surveil users, Extract data, Analyze for insights, and Manipulate for impact. The SEAMs paradigm is embedded as reinforcing feedback cycles in computational systems that mediate, and seek to control, aspects of human experience. Fronting that SEAMs paradigm are unbalanced multisided platforms (treating patrons as mere users), Institutional AIs (consequential and inscrutable decision engines), and asymmetrical interfaces (one-way device “screens,” environmental “scenes,” and bureaucratic “unseens”). Behind all this tech, SEAMs-based feedback cycles continually import reams of personal data, and export concerted attempts to influence users. While holding accountable these Web platform ecosystems is absolutely necessary work, by itself it does not engender true systems change. The approach suggested here is to challenge, and eventually replace, the underlying SEAMs paradigm itself with a far more human-centric one. The proposed HAACS paradigm is premised on a different approach – human autonomy and agency, via computational systems. Rather than feed controlling tech systems, the HAACS paradigm supports new ecosystems that empower ordinary human beings. This means building institutions, governance frameworks, and technologies that: • Enhance and promote human autonomy (thought) and agency (action); • Conceptualize personal data as flows of digital lifestreams, managed by individuals and communities as stewards under commons and fiduciary law- based governance; • Introduce trustworthy entities, such as digital fiduciaries, to help manage individual and collective digital interactions; • Create Personal AIs, digital agents that represent the human being vis-a-vis Institutional AIs operated by corporate and governmental interests; and • Craft symmetrical interfaces that allow humans to directly engage with, and challenge, controlling computational systems. Put more simply, these proposals translate into two compact terms: the human governance formula of D>=A (our digital rights should equal, if not exceed, our analog rights), and the technology design principle of e2a (edge-to-all). While the Age of Data remains in its infancy, time is growing short to challenge its many underlying assumptions. The proposed new HAACS paradigm represents one such opportunity. HAACS relies on design thinking precepts, and embraces a holistic, collaborative, systems-informed approach. Some real-world proposals in Appendix A leverage multiple ecosystem-building opportunities simultaneously across technology, market, policy, and social environments.
