The development of quantum computers with dozens of qubits does not necessarily imply that there are now people who fully understand quantum mechanics or that nobody understands digital electronics. Quantum mechanics is a complex and mathematically rich theory that describes the behavior of quantum systems, including the principles that underlie quantum computing.
While the construction of quantum computers demonstrates practical applications of quantum mechanics, it does not mean that we have a complete understanding of all its intricacies. Quantum mechanics is still an active area of research, and many aspects of the theory are still being explored and understood by scientists and physicists.
Similarly, digital electronics, which is based on classical physics and the principles of digital logic, is a well-established and widely understood field. The development of quantum computers does not undermine our understanding of digital electronics. In fact, classical computers and digital electronics remain essential for the control and operation of quantum computers.
It is important to recognize that quantum computing is a distinct field that builds upon both quantum mechanics and classical computer science. While advancements in quantum computing contribute to our understanding of quantum mechanics and its practical applications, they do not diminish the knowledge and understanding we have gained in the realm of digital electronics and classical computing.
