I really thought that Bing + OpenAI could take a slice out of Google, but this looks very competitive (based on the slick marketing video). And it's all Google's own tech unlike the Microsoft deal.
And it's pretty clear (from their own words) that regard for that risk held Google back in aggressively releasing such products.
Now that this phase is over, I expect MS to fully acquire OpenAI to better signal that they are committed to full-spectrum AI products, as Google is doing this week.
As of today, Microsoft has GitHub copilot in VScode and a bunch of other editors. Google Companion isn't released.
If Google were capable, and wanted to respond to Microsoft robustly, I would have expected both of these to be available right now immediately after Google I/O.
Instead neither have happened. I expect Google's decline into irrelevance to continue.
Edit: The comment I was replying to appears to have edited their comment to make this one no longer relevant.
