I'd argue that a lot is changing, but it's a hard thing to do. We have processors with hundreds of (noisy) qubits. We have error correction schemes (that are not realisable yet though). We're exploring multiple different approaches to qubits, from superconducting ones to topological qubits. I don't think I've seen any hand waving of potential issues by anyone. Everyone acknowledges it is hard. Is your complaint simply that it's taking a long time? Or can you point me to some of the "hand waving" claims you refer to?
