PCIe was a bottleneck in consumer boxes, but that wasn't the whole problem. Optane's low latency and write endurance looked great on paper, yet once you put it behind SSD controllers and file systems built around NAND assumptions, a lot of the upside got shaved off before users ever saw it.
"Just make it a faster SSD" was never a business.
