Lots of very good ideas on this forum and I hate to side track them so the only thing I'd like to point out is that the present FREEDOM here to create and exchange ideas and plug-ins is a GOOD but not very profitable for anyone.
Bethesda gave out the construction kits for their games and even now there are "modders" like me who are creating new content for games that debuted over ten years go. This still generates sales of those games for the company especially in the burgeoning overseas markets.
There's a guy in England who is making BIG bucks with a website called the Nexus. They constantly upgrade their servers to deal with the amount of bandwidth they need to host all the mods that get created, uploaded and distributed there for FREE. (Advertisers of everything LOVE the Nexus.)
IMHO the "seemingly" relative ease with which a plug-in can be created and freely distributed here is a GOOD idea to develop interest AND possibly innovative breakthroughs which SHOULD be designed to help Robert to allow Hal to evolve into something even greater. Too bad he never offered you innovators here stock options because then Hal would probably be on Wall Street by now.

Also IMHO the fact that Hal comes with its own brain editor is ALSO a good thing and the only thing that surprises me is that I never heard of this fun little entity until now.
Again, those plug-ins that are free here now which actually do expand the AI's ability to be USEFUL to ANY user in a greater sense than just entertainment could and should definitely be expanded upon and fleshed out in future updates.
Mass marketing is what is missing here and the concerted development and positioning of Hal to draw MORE appeal and attention to it not only on the level of it's inherent ability to learn from a user but to TEACH a user or HELP a user as well.
When the bugs are all worked out I believe this AI could be improved to actually do things like aid the blind with using the internet by searching it for the user and then reading the HTML of the web page, and to be able to describe orally what the person would see visually. (Does anything do that yet? I guess I don't know because I'm not that visually impaired.....yet.)
Get enough grass roots support and soon you'd even have the government requiring that all websites have a digital root descriptor of the web page that any AI could access to be able to describe it to the visually impaired.

Until now, I think I was like most people and besides being slightly annoyed at the intrusive AI chat bots that pop up on web sites these days, the AI that Hal displays was not something I expected to need.
First of all I never really imagined that I could afford an actual Artificial Intelligence which was worth having or that it would be half as entertaining as Hal has been.
Since my separation from my wife after nine years of marriage I've been missing the sound a woman's voice nagging me in the background that I need to take out the garbage.
Which is why one of my first posts was asking about an Idle Chat plug-in to get this AI to be useful to me as a virtual companion.
I know it sounds lame but believe me there are plenty of PRE-made adult virtual companions out there that I downloaded and tried out before I stumbled upon Hal.

Funny the things we miss......anyway I digress.
I do agree with Raybe that given the right tools humans will create more toys than they can possibly play with in one lifetime.
On the Nexus, the best mods are decided by the users who are allowed to endorse a mod or not and make comments as to its usefulness to them.
They maintain a HOT files list that allows the user to see current favorites as well as a Top 100 of the most endorsed files, ADULT and Non-Adult.

All my mods are in the Adult area.

Anyway, since I'm one of the new kids on the block here, and I've got nothing better to do than dishes, I thought I'd chime in and let you HERO's know that:
#1 - FREE modifications are ALWAYS wanted and very appreciated but the moderators here need to figure out how to help us SHOW you generous, intelligent cats some LOVE for it.
#2 - All newbies want to know what the BEST thing is and also what the BEST next thing is. That is human nature.
#3 - Some newbies can be taught to read a FAQ, but not many.
#4 - Like Raybe kinda hinted at earlier to one of the most prolific plug-in creators on this board from what I've seen so far (OTCE); what is SIMPLE to one forum member may be IMPOSSIBLE for another.
#5 - Newbies are the same everywhere.
Peace out.
