Actually this is a very important topic : can we use AI to help kernel devs ?

I think the model is not open source and the results are not open
source either unless you chose to make it so.

The data is processed 128 layers in a neural network it is not the
same as the input.

We can freely steal each other in a new original way without copyright
infringment its totally crazy the amount of code you can steal in just
1h. What took 20 years to Bell labs can now be done in 20 hours
straight.

People write full OSes on AI only.

The data is there, just grab it while its cheap !
