In contemporary societies shaped by rapid technological and social change, the meaning of literacy has expanded beyond basic reading and writing. I strongly agree that the truly illiterate in the twenty-first century are those unable to learn, unlearn and relearn. Adaptability has become a core competence, determining whether individuals can remain relevant, employable and informed in a volatile knowledge economy.

First, modern workplaces demand continuous learning as tools, roles and industries evolve quickly. Workers who cling to outdated methods struggle when automation or new platforms are introduced. For example, employees who resist digital systems often face reduced productivity and job insecurity, whereas those who relearn skills can transition smoothly and sustain long-term careers.

Admittedly, traditional literacy remains essential for participation in society, and without it learning is difficult. However, basic literacy alone no longer guarantees understanding or sound judgement. In an era of misinformation, people must unlearn false beliefs and relearn verified knowledge, or they risk being manipulated despite being able to read fluently.

Overall, the capacity to learn, unlearn and relearn defines literacy in a dynamic world. While reading and writing form the foundation, adaptability determines meaningful engagement with change. Therefore, I agree that inflexibility, rather than illiteracy in the traditional sense, is the greatest barrier to personal growth and social participation today.
