We know natural evolution is just refinement (albiet slowly), due to natural selection of a population to an environment, over billions and billions of numbers in the population over millennia, and hence why as time goes on, machined shapes become more organic in nature.

That's what computer models can do. Instead of cut and pasting millions, or even billions of different combinations, the machine can hone in on a more efficient design in the matter of weeks, days, or even hours.

Instead of baiting everyone into an argument no one wants to have, how about explaining to us what neural nets are, or asking how machine learning can be used to make you go faster.

Not baiting anyone, just making a comment, forgive me if I don't post correctly.

I read through this thread again.

I think that GM used a nascent approach with this when they altered the morphology of the LS7 rocker arms in an effort to change the natural frequency of the valve train. The mass was kept the same.

Speaking of GM and LS rockers, ask AI if a roller rocker tip is necessary, how it is beneficial and what is the lifespan compared to a radius tip.

Topology optimization using modal frequencies as a design constraint has been available to analysts/engineers since the late 1990's. Interestingly enough, Optistruct's first customer was Dr. Keith Meintjes of GM. So it's not a reach to surmise that a modern LS7 (2005 vintage) used this kind of technology. The original LS7, I can't speak for. Fundamentally, optimization uses constraints and an objective to find "local minimums" in the solution space that meet all conditions.

AI will write you reports for school and work. Friend is already using it for work. Scary when you think about the full implications.

It was always going to come to this ...... the 'SkyNet' reference earlier in the thread isn't lost on the majority of people, but as always we're mostly along for the ride

It could quickly get to the point where the negatives outweigh the benefits, and it's already too late to put the Jinn back in the bottle ...... definitely a case of 'be careful what you wish for'

I'm always wary of people who place an over reliance on technology, for the sake of it ....... a 'bathing in reflected glory' type of deal ....... and no, I'm not a Luddite
