Microsoft now has implemented "compare with Bing chat" button when you visit Google Bard in Edge
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?
at that point i consider it a microsoft tradition to do the "hey, i see you're using Y, we have a similar product called Z and it's better, do you want to try it?"-routine no one asked for.
"No one asked for this" should be Microsoft's tag line. Rather than fix problems that have been around for years - decades in some cases - they just keep adding crap that no one wants or asked for.
