Of course Google (or any other company) aren't going to blatently lie in a letter to investors (that kind of thing gets you sued) but it's pretty easy to spin words to sound more impressive than they may actually be.
Using the list provided, one example
"caption over a billion videos in 10 languages on YouTube;" - This doesn't say how accurate the captions acutally are. In my experience youtube captioning even of english dialect isn't exactly great. For one example try turning on the captions on this https://www.youtube.com/watch?v=bQJrBSXSs6o
so it's true I'm sure to say they've captioned the videos AI based techniques, but that doesn't mean they're a perfected option.
Also (purely anecodtally) Google translate also isn't exactly perfect yet either...

... I don't think I understand that video even with my own ears. YouTube captioning has actually significantly improved from it's previous hilarious state
Maybe true but they are words that are about things which are either true or not true. Has nothing to do where the words were shared. Saying they are on an investment letter so not relevant seems very short sighted.
But just looking at the last 12 months it is folly to say we are moving to a AI winter. Things are just flying.
Look at self driving cars without safety drivers or look at something like Google Duplex but there are so many other examples.
