Actual figures for CoQA from the link above: No.1 is 86.8%; no.5, 81.4%; no.20, 66.5%. No.5, though quite impressive (humans are at 88.8%), still give about two-fifth more errors than no.1.
These technologies tend toward natural monopolies as users tend to choose among the top 3-4 providers which allow them to spread costs, lower prices, and acquire yet more data. The winners at the right time tend to hold long-term monopolistic/oligopolistic power, until a major breakthrough happens.
Also, all results in the top 20 from the same link are from either the US or China (except for a couple of anonymous results). At least in this subfield, there could be only two national contenders, despite many key papers being open.
Exact algorithms, implementation details, and system engineering and integration count.
