When you visit the Google’s chatbot bard’s website in Microsoft Bing. A New Button pops up besides the search bar which lets you compare bard results with Bing chat’s. I have no idea why they implemented this, well maybe to show off the their chatbot is better than bard or something?
This will probably work for a lot of people, since as much as we hate this kind of marketing the products are genuinely competitive and many people will just pick the better solution.
If you ignore the improvement to Edge and Bing(AI) now it’s out of spite of this polarising marketing, but just be aware that you’re not the majority that this advertising is aimed at.
