I made xmas dinner this year, as I always do. It was pretty easy.
I had a basic plan, made up a menu suited to my family and my limited ability, ensured its legality, including license to serve and consume alcohol to my family on my premises, made sure I had all the ingredients I needed, checked I had recipes and instructions where necessary. I had the tools, equipment and working space I needed, and started early enough to do it all in time for the planned delivery. It was successful.
That is pretty much what you have to do to make anything, from a cup of tea to a space station, though complexity, cost and timings may vary.
With conscious machines, it is still basically the same list. When I check through it to see whether we are ready to make a start I conclude that we are. If we make the decision now at the end of 2013 to make a machine which is conscious and self-aware by the end of 2015, we could do it.
Every time machine consciousness is raised as a goal, a lot of people start screaming for a definition of consciousness. I am conscious, and I know how it feels. So are you. Neither of us can write down a definition that everyone would agree on. I don’t care. It simply isn’t an engineering barrier. Let’s simply aim for a machine that can make either of us believe that it is conscious and self aware in much the same way as we are. We don’t need weasel words to help pass an abacus off as Commander Data.
Basic plan: actually, there are several in development.
One approach is essentially reverse engineering the human brain, mapping out the neurons and replicating them. That would work, (Markram’s team) but would take too long. It doesn’t need us to understand how consciousness works, it is rather like methodically taking a television apart and making an exact replica using identical purchased or manufactured components. It has the advantage of existing backing and if nobody tries a better technique early enough, it could win. More comment on this approach: http://timeguide.wordpress.com/2013/05/17/reverse-engineering-the-brain-is-a-very-slow-way-to-make-a-smart-computer/
Another is to use a large bank of powerful digital computers with access to large pool of data and knowledge. That can produce a very capable machine that can answer difficult questions or do various things well that traditionally need smart people , but as far as creating a conscious machine, it won’t work. It will happen anyway for various reasons, and may produce some valuable outputs, but it won’t result in a conscious machine..
Another is to use accelerate guided evolution within an electronic equivalent of the ‘primordial soup’. That takes the process used by nature, which clearly worked, then improves and accelerates it using whatever insights and analysis we can add via advanced starting points, subsequent guidance, archiving, cataloging and smart filtering and pruning. That also would work. If we can make the accelerated evolution powerful enough it can be achieved quickly. This is my favoured approach because it is the only one capable of succeeding by the end of 2015. So that is the basic plan, and we’ll develop detailed instructions as we go.
Menu suited to audience and ability: a machine we agree is conscious and self aware, that we can make using know-how we already have or can reasonably develop within the project time-frame.
Legality: it isn’t illegal to make a conscious machine yet. It should be; it most definitely should be, but it isn’t. The guards are fast asleep and by the time they wake up, notice that we’re up to something, and start taking us seriously, agree on what to do about it, and start writing new laws, we’ll have finished ages ago.

Recipe & instructions
I’ve written often on this from different angles:
http://timeguide.wordpress.com/2013/02/15/how-to-make-a-conscious-computer/ summarises the key points and adds insight on core component structure – especially symmetry. I believe that consciousness can be achieved by applying similar sensory structures to internal processes as those used to sense external stimuli. Both should have a feedback loop symmetrical to the main structure. Essentially what I’m saying is that sensing that you are sensing something is key to consciousness and that is the means of converting detection into sensing and sensing into awareness, awareness into consciousness.
Once a mainstream lab finally recognises that symmetry of external sensory and internally directed sensory structures, with symmetrical sensory feedback loops (as I describe in this link) is fundamental to achieving consciousness, progress will occur quickly. I’d expect MIT or Google to claim they have just invented this concept soon, then hopefully it will be taken seriously and progress will start.
Tools, equipment, working space: any of many large company, government or military labs could do this.
Starting early enough: it is very disappointing that work hasn’t already conspicuouslessly begun on this approach, though of course it may be happening in secret somewhere. The slower alternative being pursued by Markram et al is apparently quite well funded and publicised. Nevertheless, if work starts at the beginning of 2014, it could achieve the required result by the end of 2015. The vast bulk of the time would be creating the sensory and feedback processes to direct the evolution of electronics within the gel.
It is possible that ethics issues are slowing progress. It should be illegal to do this without proper prior discussion and effective safeguards. Possibly some of the labs capable of doing it are avoiding doing so for ethical reasons. However, I doubt that. There are potential benefits that could be presented in such a way as to offset potential risks and it would be quite a prize for any brand to claim the first conscious machine. So I suspect the reason for the delay to date is failure of imagination.
The early days of evolutionary design were held back by teams wanting to stick too closely to nature, rather than simply drawing biomimetic idea stimulation and building on it. An entire generation of electronic and computer engineers has been crippled by being locked into digital thinking but the key processes and structures within a conscious computer will come from the analog domain.
