People (with 140+ IQs or otherwise) also regularly mistype, don't notice, and then trust the computer anyway. Replacing one type of potential error for another is not a win. I would be unsurprised to find out that errors in typing outstrip errors in basic math for the typical gamer.
I would be very surprised to find that, myself. Neither of us have any evidence though!
And, if it were being presented as a selling point as a solution for those with particular issues, you'd not have heard a peep from me. My brother had cerebral palsy, so I know well the adaptations one may need to make for those with disabilities. So, if you have an honest trouble with the math, then by all means use a machine to do it for you.
But, the presentation I was responding to was not of that form, so please do not assume I'm addressing the specific case, rather than the general.
Computers are great for many things. They can automate difficult tasks, and enable things that humans cannot do otherwise. I am all for using mechanization to solve problems. I am not for using mechanization to solve non-problems, however. Technology is great. Technology for the sake of technology is not great.
But it's
not a non-problem, that's the thing, as I've explained. It may be a non-problem for you, that's great. I play with very smart people in high-end jobs who got As though high-school and university, very smart people however you measure it - some of those people are much better off tracking stuff digitally, where possible - none of them but me have any diagnosed issues, but that's the thing, this assumption that it's a non-problem is just an assumption and a wrong one.
My ADHD wasn't diagnosed until I was 20, treated properly until I was 22. I went through life with people telling me I was being lazy or cheating or whatever using computers and calculators where I could (something my two math-genius friends disagreed with - they always thought it was fine), implying that I was just dumb or not trying hard enough, or whatever, and it was all nonsense.
So when I see other people messing stuff up or wanting to use a digital/automated method to track something, I feel like I know better than to sneer. If they were uneducated, if it was just "I don't know how to do math", I'd want to teach them and help them - that isn't the issue. If you slam the game to a halt and make them focus on the math, yes, they will get right, but how, exactly, does that help? My view is that it does not.
As for the problems from technology, I reject any suggestion that they are to do with automation, spreadsheets, or the like. That flies in the face of my experience using laptops in games since the mid-90s.
My experience is very clearly that it's communications tech that's a problem, and it's much more of a problem when it's new than when it's a year or three old. Mobile phones, then text messages were a problem for us in the mid-late '90s, but then they got under control. Twitter was a problem three years ago, but now it's gone away. The only thing that remains a problem from time to time is that some people's employees/SOs can't leave them alone, but honestly, better than goes via text than phone calls (the one SO who insists on phoning every hour or two causes more disruption than the rest put together).
If people are watching YouTube or whatever during your game - your problem ain't tech. It's either your game, or that player.
