Antenna Optimizers available for ham radio, basically 4NEC2, Mmana and AutoEZ, 
are tools, calculators, to save us some time, but you still need to know what 
to do.

Those optimizers are not AI yet, you can't say "optimize this antenna", and get 
it, it is not like that.

Good story.  Reminds me of my purchase of a TI scientific calculator back in 
the 1970's.  It had a factorial key (!).  You could enter 69! and the display 
would go blank for about 20 seconds while the calculation was being performed.  
I just ran the same calculation on this PC and the 
result:1.7112245242814131137246833888127e+98
came back in the blink of an eye. <grin>
