No offense, but he said what we all knew deep down tbh. Qc is far off and we all believed in the potential… without a clue when that would be obtainable
In 2021, Rigetti demonstrated, for the first time, the entanglement between two qubits fabricated on two separate chips. This work was published in Nature.
In 2021, Rigetti discovered that quantum circuit Born machines show superior performance compared to restricted Boltzmann machines in modeling financial data.
In 2024, Rigetti discovered a new fabrication technique that improves the relaxation time of superconducting qubits. This work was published in Nature.

In 2024, Rigetti discovered a new technique for adjusting the resistance of Josephson junctions at room temperature. This discovery makes it easier to scale quantum computers based on superconducting qubits. The results were published in Nature.
In 2024, Rigetti and Riverlane successfully demonstrated low-latency quantum error correction achieving a mean decoding time per round below 1 microsecond.
In 2024, scientists proposed new ideas to scale superconducting quantum computers to thousands of qubits. https://arxiv.org/pdf/2411.10406
At the end of 2024, Rigetti built a quantum computer with 84 qubits with a two-qubit gate fidelity above 99%. This quantum computer has a similar performance to Willow, the chip built by Google.
Seems like they are making incremental progress but still far from having truly practical or scalable applications yet. It will be impressive once you can run general purpose models like climate simulations with quantum computers.
I didnt read through all this but that last bullet point, Rigetti's chip is nowhere near as good as Google's Willow. Their two qubit gate error rate is an order of magnitude larger than Google's, their coherence times are 5x shorter which means you can't run very long circuits and presumably they higher readout error rates.
In 2019 or so, many of their theorists left for Google and I think many of their hardware team also left. Their original CEO, Chad Rigetti was one of the first to work on superconducting qubits, and I heard he kinda sucked to work for, but he also is no longer at the company. While they likely have brilliant people still, It seems like they are pushing the business hard to make money, but why would anyone want to rent time on a device that doesn't do anything special outside of their own research on noisy, not useful qubits.
Unless there is some major breakthrough in superconducting hardware that isn't patented (or its discovered by Rigetti) I don't see how they will be able to compete with Google and IBM.
AGI is not 5 years away. We already have enough hardware to achieve brain level computational power, yet models with general intelligence (human level problem solving capacity across all domains, figuring shit out on the go without prior training) are nowhere in sight. In case intelligence also includes sentience and self-awareness, then it's even further away.
