It's not that google isn't capable of providing much better search. It's that they are driven by interests other than the users actually doing the search. Google has some of the most advanced tech and engineers in the world. But they also have an endless list of issues they must address - no facial recognition, no racial bias, no sexual content, filtering specific politics, supporting partners, etc.
They also face huge amounts of legal pressure to make GI less useful and stripping out features so that more people follow through to the site and see the adverts.
