For instance, if you want a jet aircraft sim good enough to train pilots, you will likely need to have structural characteristics of all the parts, since high-performance jets flex under load, things act in unexpected ways when you push to the limits etc. You need to model things like the moment of inertia of the elevators, rudder, ailerons and so forth. There are no shortcuts, if your sim precision is critical, as it is in some cases.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:9.5pt;font-family:"Arial",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:9.5pt;font-family:"Arial",sans-serif'>If we want to get AI, we have one really good example of I. We have one good example of what we need, one example of a machine which can generate software. To create a sim which can write software, we simulate the one example we have of that. To do that, we sim every subsystem, every single one, all the way down. Then we run it as a background process on a bunch of interconnected computers. We might find we can simulate a second of human-like thought per hour. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:9.5pt;font-family:"Arial",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:9.5pt;font-family:"Arial",sans-serif'>This approach requires that we understand how dendrites and glials and synapses and all the rest of it works.

I noticed the text hasn’t changed all that much in the last 20 years. The insights offered in the mainstream courses is really not progressing all that much, which tells me we need to try something else.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>spike<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:black'><o:p> </o:p></span></p></div></div><div><p class=MsoNormal><o:p> </o:p></p></div></div></body></html>
