Why is Siri coming when not using

I find that it is relatively easy to launch Siri accidentally in my 2019 16" MBP.

The reason why it happens to me is that when typing and pressing some keys in top right of the keyboard (notably the delete key) I sometimes accidentally touch the Siri "button" in the touchbar.

As Eau Rouge said, if you don't ever use Siri, the best thing is to turn it off.

If you do use it: did this happen one time, or does it happen often? You may check to see which keyboard shortcut is assigned to Siri.
