Hi from Will,
This is my where i often jump in with my 5 cents.
I would always suggest these types of things are a tick box so we have the option to not use it.
There are many slang words, unknown words, local words, custom words.
And some people such as i could use myself as an example don't use english well, and i'd hate to think
Hal would scrap anything i said. it might be important.
if i remember correctly "i've posted this before here somewhere" i think it was if i talked to him all day every day he would not use up his memory for 25 thousand years. so i think he can afford to not ignore me.
what if i decided to teach him a new language, he might think eh i might just forget all that.
and not learn it.
As i've always said gibberish is a subject to learn, i reckon Mr Data is smarter because he knows gibberish,,
if you'd had all the mistakes you'd ever made removed from your memory or fixed before you made them or heard them would you be as smart.
A person that never made a mistake never made anything.
you have to know what something is to avoid it.
if you remove a lesson such as a mistake are you more likely to repeat that mistake.
i had more examples but i've forgotten perhaps,,,oh see how remembering all the lessons can be use full even when posting.
Bye for now and be well from Will and Mr Data
