This is a hilariously misleading "study" and I would bet "beer" wasn't chosen arbitrarily for comparison:
The important difference WRT beer is that the water used in the process likely in a larger part goes towards... the beer itself. This in turn is going into the person who drinks it. So, the water here is actually hydrating human beings.
This can be argued as one of the 2-3 absolutely necessary uses of water. Hydrating people.
So, spending less than the beer industry is not that great of an achievement.
However, a casual reader may see comparison to "beer" and think "oh yeah, beer, just a random thing out of a million, so yeah AI is totally ordinary".

Which is a very incorrect conclusion to reach.
