Certainly, Bitcoin and the associated technologies may not be utilzed by everyone directly, now, and perhaps not ever. Which is due to the reluctance of many individuals to embrace new technology or their specific circumstances. Nevertheless, the widespread adoption may occur if Bitcoin becomes the foundational framework for global payment systems, similar to how almost everyone on Earth has interacted with TCP/IP in some capacity, even if only minimally, and only a small fraction of people fully understand it or even know it. I anticipate a similar trajectory for Bitcoin technology.
