*Recovered fragment // Speculative Accessibility // Week 1*

Two frameworks — one practical, one theoretical — are both trying to answer the same stubborn question: why is the digital world still inaccessible, and what would it actually take to fix it?

Rungwell starts with an organizational diagnosis. Companies fail at accessibility not through malice but through incomplete maturity — they lack the right strategy, the right training, the right leadership to embed inclusion into their culture. The remedy is a roadmap: a maturity model of its own, the Rungwell Maturity Model that moves an organization from reactive to leading, measured through customer satisfaction and legal compliance, anchored to the WCAG standards that constitute the industry’s current floor.

The Tyrer Framework begins one level deeper. It doesn’t treat inaccessibility as a process gap. It treats it as a law of nature — specifically, Tyrer’s Law: the structural tendency of human-designed systems to drift toward the visual, because sighted designers reach for visualisation as a thinking tool. This isn’t a failure of goodwill. It’s an architectural constant, as predictable as entropy.

Where these diagnoses differ, so do the proposed solutions. Rungwell works within Classical Accessibility — retrofit, adapt, comply. Meet the standard; serve the user. The Tyrer Framework calls this accommodation, and argues it isn’t enough. What it proposes instead is Generative Accessibility, grounded in the Tyrer Doctrine: no critical information should be locked behind a single sensory channel. Accessibility is reframed not as inclusion policy but as Information Integrity — an engineering requirement sitting alongside server redundancy and data integrity in the hierarchy of things a system must guarantee to function properly.

The scales at which each framework measures progress are equally divergent. Rungwell’s maturity model is an organizational instrument — it tells any company how far along the maturity curve they sit. The Tyrer Accessibility Scale is civilizational, modelled explicitly on the Kardashev Scale. It tracks humanity’s trajectory from Type 0 (Visual Dominance) to Type III (Perceptual Sovereignty), measuring not energy use but the progressive elimination of information casualties — people excluded from knowledge and participation by the sensory assumptions baked into how information is delivered.

Both frameworks converge on AI as the most significant factor in play, but read its implications very differently. Rungwell treats AI as a powerful tool in the accessibility service stack — something that helps navigate, adapt, and assist. The Tyrer Framework identifies it as a Structural Break: for the first time in the history of human-computer interaction, technology can move from interface-first (visual) to intent-first (semantic). That’s not an incremental improvement. It’s a fork in the road. AI could weaken Tyrer’s Law by enabling native non-visual interfaces that never needed visual mediation in the first place — or it could accelerate the problem by generating even denser layers of visual complexity. Which path it takes is not a technical question. It’s a design philosophy question.

Read together, Rungwell describes the world we need to navigate right now, and the Tyrer Framework describes the world we need to build toward. One offers the ladder. The other names the ceiling.
