There are still tons of problems that can not be solved even with the most powerful supercomputer. Taking simulating medicines as an example, it may take thousands of years to simulation to the interaction between millions of atoms in the human body and the chemicals.
To tackle these problems, a universal platform for universal quantum computer based on spin qubits that is compatible with existing semiconductor technologies is now on its way. The technical problem now facing is how to gain control over the coupling between qubits. So the architectural element has now developed to overcome this problem.
