Carl2, Lightspeed, et. al.,
I think the data to which you have referenced is not indicating that there is a downloadable "enhanced" or "updated" version of Hal. Those stats indicate how many sentences, conversations and people the Online Hal version has had with visitors and other users. Notice, the totals have changed since Carl reported the numbers in his post.
Here are today's (3-5-2016) data:
As of Saturday, March 05, 2016 Hal's knowledge is based
on information learned from:
22,997,470 sentences from
3,940,439 conversations with
1,470,799 people
Look at the opening page at the top, yep, that Hal.
It would be nice if we could enjoy the benefits of Hal's learning. (I just hope all the badness, misspellings, grammar, cursing, slang, etc.) has been removed...at least for my version.
