Another thing which can be gleaned from the progression of ReCAPTCHA from v1 - enter street names and house numbers into this box please - through v2 - identify images with street signs, shop fronts, buses, cars - to v3 - only Chrome/Firefox/Edge/Safari users welcome is that Google Maps (and related units) no longer needs ReCAPTCHA users to read those street names and house numbers as that task is now reliably performed by software, nor does it need help to separate shop fronts from normal facades or traffic signs from billboards. Now that these tasks can be handed over from mechanical Turks to the server farm ReCAPTCHA can be turned to other purposes like giving Chrome an extra boost.
