What technical problems need to be solved before it is readily available?

Before widespread availability of certain technologies, several technical problems often need to be addressed, including scalability, interoperability, and security. For instance, ensuring that systems can handle large volumes of data efficiently is crucial for scalability. Interoperability issues must be resolved so that different technologies can work seamlessly together. Additionally, robust security measures are essential to protect data and user privacy, which can be a significant barrier to adoption.
