I make a living their using their games (under 1800) and the blunders are incredible. No whiff of silicon in these games.
(without a doubt machines appear in some of the 2200+ games - I do not go near them.)
This is the latest...er...instructive blog/column:

(not on a hit hunt, they often get 15,000+ to 20,000)
The gang there do not play blitz (well not officially ) you have days to make a move and still the blunders come.
The main reason is because they have so many games on the go at once and race through them. (40+ games at once is not uncommon.)
Which brings me onto this. (Black to play)
Don't be appalled at white playing on. I have an RHP database of 'currently' 13,991 games ending in stalemate.
If one player there has been stalemated or chucked a won game due to stalemate then lesson learned,
if they sense the remotest chance of a stalemate then it goes the distance to mate....or stalemate.
(my job there is to point out all the missed mates before stalemate.)
Also please remember the vast majority are home and casual players, the book, magazine, DVD's buyers - the very core of the game.
So what happened next? (the player concerned actually sent me the game.)
Black was skipping through his games, as you do, I've blundered but not quite as badly as this.
It was a blunder you are hardly likely to see in an OTB game (unless someone has an example - please!)
Black forgot he was Black , thought he White and resigned 1-0!
Been chuckling about that all day. There are a few examples of players resigning in a won game But has anybody
ever forgotten what colour they were in an OTB game and resigned. I've not done that one yet...touch wood.)
