We are part of the massive diversity. We are not actually disabled but we are living with a disability.
The hardware and software we are using are disabled. The hardware and software need to be enabled to work with the range of human diversity.
The world is getting older, by 2030, There are going to be more people in retirement age than babies in the United State of America. The number is expected to reach 78 million many acquire disabilities but not identify as a person with disability. Currently 8% of the world’s population is above 65 years which is expected to rise to 17% by 2030 from 901 million to 1.4 billion. (Source)

What is Universal Design?
It is the design and composition of an environment so that it can be accessed, understood and used to the greatest extent possible by all people regardless of their age, size, ability or disability. This is not a special requirement, for the benefit of only a minority of the population. It is a fundamental condition of good design. If an environment is accessible, usable, convenient and a pleasure to use, everyone benefits from it.
In 1997, Ronald led a working group of architects, product designers, engineers, and environmental design researchers, to create the 7 principles of universal design to help guide the design process of environments, products, and communications.
Here is a summary of the 7 principles: -
Principle 1: Equitable Use
The design should be useful and marketable to customers with diverse abilities.
Principle 2: Flexibility in Use
The design contains a wide range of personal preferences and abilities.
Principle 3: Simple and Intuitive Use
Make sure the use of the design is super easy to understand, regardless of the experience, knowledge, language skills, or current concentration level the user have.
Principle 4: Perceptible Information
The design transmits necessary information efficiently to the user, irrespective of ambient conditions or the user's physical abilities.
Principle 5: Tolerance for Error
The design should be able to reduces risks and the adverse consequences of accidental or unintended actions.
Principle 6: Low Physical Effort
The design should be used effectively and easily and with a minimum of exhaustion.
Principle 7: Size and Space for Approach and Use
Right size and space is offered for approach, reach, manipulation, and use regardless of user's body size, posture, or mobility.
