Deep Blue was only innovative in that it was specialized hardware for this type of search. The algorithms it used were well-established, and as there was no way to play it as a piece of hardware without great expense, there wasn&#x27;t really a reason to keep it around.<p>Chess engines you can run today, for free, on your own laptop, are far and away better than Deep Blue (and <i>any</i> human), and I believe still don&#x27;t reach Deep Blue&#x27;s raw speed.
