> Multiple hominid species on Earth have had a technology gap on an unfathomable timescale. Indeed, the Denisovans developed stone tools tens of thousands of years before our own species.

Nonsense. Hominin toolmaking and tool use go back more than 2 million years, long before the last common ancestor of humans and the Neanderthal/Denisovan branch. About all we can say about Denisovan tool use is that their technology, circa 100,000 or 150,000 years ago, was roughly the same as contemporary Neanderthal and human technology.
