Curb cut effect
The curb cut effect is the phenomenon of disability-friendly features being used and appreciated by a larger group than the people they were designed for. The phenomenon is named for curb cuts – miniature ramps comprising parts of sidewalk – which were first made for wheelchair access in particular places, but were also welcomed by people pushing strollers, carts or luggage. Curb cuts are now ubiquitous and no longer widely recognized as a disability-accessibility feature. Another example is hearing people using television closed captioning.
The curb-cut effect
The curb-cut effect illustrates how when we design to benefit disadvantaged or vulnerable groups we end up helping society as a whole. Angela Glover Blackwell explains how campaigning by students with disabilities in Berkeley in the early 1970s led to adding curb cuts to the Berkeley sidewalks to make access easier for those in wheelchairs. Yet it wasn't just people in wheelchairs that it helped. Curb cuts also made life easier for people pushing children in strollers, people using trolleys for deliveries, people pulling a suitcase, those wheeling bikes or on skateboards, and it also helps save lives by guiding people to cross at safe locations. Another example is adding closed captioning to TV that helps anyone watch in a noisy bar, a waiting room, or watching an airline safety video. Or a classic example of universal design in the OXO Good Grips range originally made to be comfortable for holding a peeler even if you have arthritis. It's also a useful analogy for "how laws and programs designed to benefit vulnerable groups, such as the disabled or people of color, often end up benefiting all," (PolicyLink) whether that be increasing broadband access, improving public transport or taking cuts out of curbs. Here's a short, fun video of Gary Karp explaining the curb-cut effect. Thanks to my patron Quintin Balsdon for sharing it with me.

AI and the Future of Accessible Work
Many countries have legislation that prohibits discrimination against people with disabilitiesa in the context of employment. For example, the U.S. Americans with Disabilities Act (ADA),b the U.K.’s Equality Act of 2010,c and European Union policyd prohibit employment-related discrimination and require employers to provide reasonable accommodations or adjustments so disabled employees can perform their jobs. More broadly, the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD)e has influenced legal frameworks across the globe. Despite these anti-discrimination policies, disabled people remain significantly underrepresented in the workforce. Employment gaps between disabled and non-disabled people exist globally.28 Among blind and low-vision Americans, for instance, only 44% are employed compared to 79% of those without disabilities.f Only 54% of d/Deaf peopleg in the U.S. are employed, compared to 70% of hearing people.8 These discrepancies are worse for multiply marginalized disabled people. For example, employment rates for disabled women are significantly lower than rates for disabled men.21

Substrates via Accessibility
The social model of disability holds that disability is produced by environments, not by bodies — that when software fails to accommodate a person’s needs, the environment is disabling them. We argue that the dominant organization of computing produces such interaction mismatches structurally: the commodity form of software requires a standardized consumer, and everyone whose needs diverge from this imagined subject is disabled by the software environment. The substrates research community has identified properties — disclosure, composability, malleability — that would address this, but the commodity form actively selects against these properties because they dissolve the boundaries on which exchange value depends. This raises a question: how can infrastructure organized against the grain of commodity logic be made durable? We find a precedent in accessibility infrastructure — sustained not by patronage but by the organized counter-power of disability rights movements. Through Allio, a system for cross-application augmentation built on accessibility APIs, we illustrate both what this foundation makes possible and where its limits lie. We argue that the accessibility case reframes the substrates programme’s central challenge as political-economic: the question of who sustains substrate infrastructure, and through what social mechanisms, is as important as the question of what properties it should have.

I have resigned as the WordPress accessibility team lead. Here is why. – Rian Rietveld
Update December 5, 2019:As I am no longer part of the accessibility team and don’t follow closely what is happening in WordPress core any more, I’d like to add to following.
Against Technoableism
When bioethicist and professor Ashley Shew became a self-described "hard-of-hearing chemobrained amputee with Crohn's disease and tinnitus," there was no returning to "normal." Suddenly well-meaning people called her an "inspiration" while grocery shopping or viewed her as a needy recipient of technological wizardry. Most disabled people don't want what the abled assume they want--nor are they generally asked. Almost everyone will experience disability at some point in their lives, yet the abled persistently frame disability as an individual's problem rather than a social one. In a warm, feisty voice and vibrant prose, Shew shows how we can create better narratives and more accessible futures by drawing from the insights of the cross-disability community. To forge a more equitable world, Shew argues that we must eliminate "technoableism"--the harmful belief that technology is a "solution" for disability; that the disabled simply await being "fixed" by technological wizardry; that making society more accessible and equitable is somehow a lesser priority. This badly needed introduction to disability expertise considers mobility devices, medical infrastructure, neurodivergence, and the crucial relationship between disability and race. The future, Shew points out, is surely disabled--whether through changing climate, new diseases, or even through space travel. It's time we looked closely at how we all think about disability technologies and learn to envision disabilities not as liabilities, but as skill sets enabling all of us to navigate a challenging world.
