Eleven years have passed since our founding. Last year, we added a simplified transaction processing function to openK and worked to strengthen inventory management and eliminate data loss. Although our software had never experienced internal data corruption to begin with, we have continued to build even more robust mechanisms under the belief that “there is no such thing as absolute safety.”
In addition, without straying from our original policy since establishment—to deliver efficiency and stress-free operability—we continued developing features such as automatically printing quotations with a single button press. As a result, I take pride in saying that our software has evolved into an even more reliable system.
Last year, generative AI technologies, including ChatGPT, advanced significantly and began to be widely utilized in software development environments. I often hear new programmers say things like, “Let’s ask AI what’s wrong with this code,” or “How should I write this process? Maybe AI can help.” I truly feel we are living in a very convenient era.
At the same time, as these technologies continue to spread, there is also a slight concern that people may stop making efforts themselves, and that human jobs may eventually disappear. However, this type of thinking has existed since the Industrial Revolution, and even more than 200 years later, we have not reached the conclusion that “humans are no longer needed.” This is one of my answers.
Going forward, computers will continue to penetrate even more deeply into our daily lives. It is anticipated that technology will support fields that humans have built through creativity and continuous effort, such as music, art, literature, agriculture, healthcare, and nursing care. As part of this trend, we sincerely hope that our software will continue to support and empower your daily operations.
