Unlikely Nikon bought AI Deep-Learning and Computer Vision innovators, Wrench purely as an ornament.
This was one of several companies, Nikon has purchased over the past decade to grow their Robotics and AI technology. This is aimed as much at precision engineering (manufacturing applications) in industry as well as Consumer imaging products (Z System). (The high speed stacked sensor announced in January 2021 flagged this R&D arena in a different division of Nikon.)
The D6 Autofocus system was developed post D5 release (2016-2019) if not they had in train earlier. The 3D Tracking AF mode premiered in the D5 and D500 (2016). It matured in the D6, announced 2019 and with Subject Recognition.... Well in as much as it's possible to accommodate SR in a DSLR architecture with restricted AF search area with an OVF.
After long experience in using and customizing my D6, it's obvious its face and eye detection algorithms, the D6 Custom Area AF modes especially, are precursors to matured technology in the Z9 (using both for wildlife).
Judging from the sustained flow of patents in sensor tech, optics as well as Autofocus tech etc registered by Nikon engineers over the past decade, Nikon is definitely not a company suffering a lack of innovation
A camera or lens takes a few years from concepts to mass production. Nikon began planning their Z System well before its launch in August 2018.

What held them back was downsizing and exiting investments in their large Consumer DSLR liabilities, as well as recovering earnings on R&D invested in high end DSLR products and technology (AF included).
Above all, besides write offs of the odd factory, clearing this big DSLR inventory demanded balancing the continuing sales of F mount products they had now identified as yesterday's ILC system. Only later could they prioritize fast tracking the new Z System.
Previously a trickle (coping as well with a pandemic obviously), release of Nikon's high end MILC products finally accelerated at the end of 2021.
So through this parallel process of balancing Z system R&D and F System downsizing (aka Exiting) Nikon Imaging has sustained earnings on the prior R&D invested in their most recent Pro tier F-mount products, including the penultimate F Nikkors (105 f1.4E, 180-400 TC14 etc), and the D5 Triumvirate - the D850 in particular which is still earning for Nikon 7 years on, albeit less demand.
The corrections in a
current DPR thread to a trending clickbait Petapixel article have more details on how Nikon skilfully restructured its Imaging Division...besides turning around the entire company; in part this entailed reshaping their Monodzukuri strategies eg production of optical elements.
The parts-bin D780, released in April 2020, presumably also has helped clear the DSLR inventory (besides selling more Z6 sensors). In parallel, while Nikon's management has been winding down F mount releases over the past decade, Nikon Imaging R&D must have been focused centrally on Z System products over the past decade.
However, it appears Nikon's factories have finite capacity to produce cameras and lenses. High quality products are risky to fast track after all. Backorders for popular products suggest this is the case....
Or write off potential earnings on DSLR investments, R&D especially? See above
This makes sense for wildlife Telephotos
AF will continue to leapfrog, and AF systems are challenging to compare objectively. Each of the trio work well on 99% of subjects
