Google does seem to be using artificial intelligence a lot. Your posts on the thread mentioned 0.45 calibre bullets as examples of the quantity of stored energy you were dealing with.

Pay a bit more for something that works.

But the bullet will be much noisier.

I use Outlook because my company does. No problems sending to co-workers.
