Quantum computing may be (practically) dead

It appears to be more of a corporate or financial issue. The scalability of quantum computing is an issue, and it wraps around the decoherence problem and quantum error correction coding. Quantum computing may follow the path of virtual reality, which was really popular in the late 80s, faded away and now has appeared again. Quantum processors may be a part of computing architecture in the future.

The thought dawned on me that maybe we can emulate black holes with optical computing. In this way the quantum decoherence can be "red shifted" so it has a lower rate of occurrence. These emulation of black holes are experiments that find analogues of Hawking radiation.
