Nobody (at least nobody respected) is claiming we (humanity) have a scalable quantum computer. There are a bunch of interesting research hardwares that have handful of qubits and things are steadily (albeit slowly) growing. But many people in the field have started expecting practically usable hardware to start appearing in the next decade. That level of ubiquitous near-term optimism is pretty new and exciting (especially when looking back to the immense progress of the last 20 years in this field).
