In case Nick Carter's VC-money infused fear-mongering is not really your thing, this article does a better job at explaining some of the recent quantum computer developments.

A snippet to pique your interest...

Qubits of any sort are extremely error-prone, and computing with them will require constant vigilance. The gold-standard protocol for error correction is called the surface code. You lay qubits out in a rectangular grid, with each one linked to its neighbor, and use the whole block to store one virtual qubit of information. Then, when some of the real qubits go haywire, the virtual qubit stays protected long enough for you to find and fix the rogue qubits. The surface code is completely reliable and thoroughly understood, but it would take thousands of real qubits to create one reliable virtual qubit. And the virtual qubits are the ones you need to perform an accurate calculation.

But over the last few years, physicists have found a way to dramatically reduce the number of real qubits they need to create the virtual ones, using quantum “low-density parity-check” (qLDPC) codes. The codes are tricky because they require linking up the real qubits to other real qubits that are far away in the array, as opposed to just their neighbors. But in return, they let you pack many more virtual qubits into an array of a given size. Neutral atoms are a natural fit for these codes, because physicists can freely move one atom across an array to meet a distant atom.
