Introductory Whining and Complaining About the Difficulty of Getting Funding to Build a Real AI

A bunch of people have said to me, recently (in one version or another), "Ben, you write so much, why don't you write a blog like all the other pundits and gurus?"

My answer was that I don't have time, and I really don't -- but I decided to give it a try anyway. Last time I tried blogging was in 2002 and I kept going for a few months, then petered out. Maybe this time will have a better fate!

What's on my mind lately? Frustration, in large part. My personal life is going great -- last year my drawn-out divorce finally concluded; my kids are finally pretty much settled into their new routine and doing well again, and my new wife Izabela and I are having a great time together.

I'm enjoying doing bioinformatics research with Biomind, and recording whacky music using Sonar4 (the first time I've hooked up a sequencer to my keyboard for many years; I'd avoided it for a while due to its powerful addictive potential).

Life is good. But the problem is: the longer I think about it, the more I write about it and the more exploratory design and engineering work my Novamente colleagues and I do, the more convinced I am that I actually know how to make a thinking machine... an intelligent software program, with intelligence at the human level and beyond.

Yeah, I know, a lot of people have thought that before, and been wrong. But obviously, SOMEONE is going to be the first one to be right....

I don't pretend I have every last detail mapped out. There are plenty of little holes in my AI design, and they'll need to be filled in via an iterative, synergistic process of experimentation and theory-revision. But the overall conceptual and mathematical design is solid enough that I'm convinced the little holes can be filled in.

What's frustrating is that, though I can clearly see how to do it, I can also clearly see how much work it requires. Not a Manhattan Project scale effort. But more work than I could do in a couple years myself, even if I dropped everything else and just programmed (and even if I were a faster/better programmer like some of the young hacker-heroes on the Novamente team).
My guess is that 3 years of 100% dedicated effort by a team of 5-6 of the right people would be enough to create an AI with the intelligence of a human toddler. After that point, it's mostly a matter of teaching, along with incremental algorithm/hardware improvements that can be carefully guided based on observation of the AI mind as it learns.

And I have the right 5-6 people already, within the Novamente/Biomind orbit. But they're now spending their time on (interesting, useful) narrow-AI applications rather than on trying directly to build a thinking machine.

I thought for a while that we could create a thinking machine along the way, whilst focusing on narrow-AI applications. But it's not gonna work. Real AGI and narrow-AI may share software components, they may share learning algorithms and memory structures, but the basic work of building an AGI cognitive architecture out of these components, algorithms and structures has nothing to do with narrow AI.

As CEO of Biomind, a startup focused on analyzing biological data using some tools drawn from the Novamente AI Engine (our partially-complete, wannabe AGI system) and some other AI tools as well, I'm constantly making decisions to build Biomind software using methods that I know don't contribute much if at all toward AGI. This is because from a Biomind point of view, it's often better to have a pretty good method that runs reasonably fast and can be completed and tested relatively quickly -- rather than a better method that has more overlap with AGI technology, but takes more processor time, more RAM, and more development time.

Although our work on Biomind and other commercial apps has helped us to create a lot of tools that will be useful for building an AGI (and will continue to do so), the bottom line is that in order to create an AGI, dedicated effort will be needed. Based on the estimate I've given above (5-6 people for 3 years or so), it would seem it could be done for a million US dollars or a little less.

Not a lot of money from a big-business perspective. But a lot more than I have lying around, alas.

Some have asked why I don't just build the thing using volunteers recruited over the Net. There are two reasons.

One, this kind of project, doesn't just require programmers, it requires the right people -- with a combination of strong programming, software design, cognitive science, computer science and mathematical knowledge. This is rare enough that it's a hard combination to find even if you have money to pay for it. To find this combination among the pool of people who can afford to work a significant number of hours for free ... well the odds seem pretty low.... (Though if you have the above skills and want to work full or near-full-time on collaborating to build a thinking machine, for little or no pay, please send me an email and we'll talk!!)

Two, this is a VERY HARD project, even with a high-quality design and a great team, and I am not at all sure it can be successfully done if the team doesn't have total focus.

Well, I'm hoping the tides will turn in late 2005 or early 2006. Finally this year I'll release the long-awaited books on the Novamente design and the underlying ideas, and following that I'll attempt a serious publicity campaign to attract attention to the project. Maybe Kurzweil's release of his Singularity book in late 2005 will help, even though he's a skeptic about AGI approaches that don't involve detailed brain simulation. I'd much rather focus on actually building AGI than on doing publicity, but, y'know, "by any means necessary" etc. etc. ;-)

OK, that's enough venting for one blog entry! I promise that I won't repeat this theme over and over again, I'll give you some thematic variety.... But this theme is sure to come up again and again, as it does in my thoughts....

Very foolish of the human race to be SO CLOSE to something SO AMAZING, and yet not have the common sense to allocate resources to it instead of, for instance, the production of SpongeBob-flavored ice cream (not that I have anything against SpongeBob, he's a cute little guy...)...

P.S. Those with a taste for history may recall that in the late 1990's I did have a significant amount of funding for pure AI work, via the startup company Intelligenesis (aka Webmind), of which I was a cofounder. We tried for about 3 years and failed to create a real AI, alas. But this was not because our concepts were wrong. On the contrary, it was because we made some bad decisions regarding software engineering (too complex!), and because I was a bad manager, pursuing too many different directions at once instead of narrowly focusing efforts on the apparently best routes. The same concepts have now been shaped into a much simpler and cleaner mathematical and software design, and I've learned a lot about how to manage and focus projects. Success consists of failing over and over in appropriately different ways!

It seems to me that the fastest way to raise the necessary capital would be to set up some form of equity instrument or a type of foundation that funds may be gathered by. Although I am by no means rich (involved in bootstrapping a more mundane endeavor) I would be interested in contributing. Can something along these lines be set up?

Hi Samantha,

In fact, both of the instruments you mention (equity and foundation) exist:

* Novamente LLC, which can take equity investments, and is oriented toward commercial uses of AGI technology

* AGIRI (AGI Research Institute), which doesn't yet have a bank account but is incorporated as a nonprofit

The problem lies in convincing people to contribute, not in setting up the formal entities to receive the money ;-)

My intention is to make a big fundraising push in 2006, after the Novamente books are published and we've put together a (mildly) spiffy demo of Novamente learning in the AGI simulation world. .

I also have some hope of getting government research funding, being based in DC and having some contacts here, but this hasn't panned out so far. I'll keep on pushing....

The problem is that seeking funds could be a full-time job unto itself, and I already spend about 2/3 of my time on bioinformatics applications rather than on AGI. So if I started spending a lot of time seeking AGI funding then I'd have no time for AGI at all, which might be the right thing to do, but would drive me nuts.... Of course, as well as paying the bills, the bioinformatics apps have the potential of eventually bringing in the $$ to fund AGI, so in a sense they're "working toward AGI", but only indirectly.

Anyway, if you'd like to make an investment in Novamente LLC or donation to AGIRI that would be much appreciated. The use of the funds will be the same in either case -- but from your description of your situation, I think a donation to AGIRI may be more appropriate. We decided a while ago that there is minimum amount for investment in Novamente LLC, because there is some overhead involved in managing the Novamente LLC membership over time. Anyway I can't "solicit" for Novamente investments through a public site like blogger.com, that violates some securities laws.)

To donate to AGIRI, you just have to write a check to AGIRI and mail it to

We will get PayPal set up for AGIRI eventually but it didn't happen yet.

Your support is much appreciated ---- "moral" and also financial if you so choose...

Yes... It's so frustrating to have to do a boring engineering job or narrow research, while you're speculating on theories of intelligence, how the mind scales its complexity by interacting with the environment etc...

But it's good that people like you and Jeff Hawkins inspire and give a good example for the younger "dreamers" like me, who're also trying to create companies and focus on the strategically most important direction.

Thanks for the inspiration!
