A very long time ago, in the 90s, we really thought that computers would make people smarter. We thought computers would sharpen people's analytical skills with logic and math, would provide them better tools to write and design things, would provide them information to help them get better answers.

Back then, there was a famous snake-oil salesman that coined the expression "computers are bicycles for the mind". He proposed an analogy: when you compare the effort humans put into personal locomotion on foot with other animals you'll notice that they spend a lot of effort to yield very little movement. But then you put them in a bicycle and things change: humans can move a lot with very little effort. Computers would do the same: increase the mind's "productivity".

Fast forward for today and we live in a world where everybody has a computer in their pockets. Ironically this change was pioneered by that very same snake-oil seller.

And when I see the consequences of it, I say to myself: "boy, we were soooo wrong!".

Law of unintended consequences? Or it is the fact that everyone is lazy and do want to remain dumb?

It’s still possible. There’s this sort of guerilla education movement in software with apps like Mathacademy and Mentava to really focus on actual learning, in a scientific way. I can say for my part that my son has been using Mathacademy and the results have been incredible.

The reason most educational software is not like this, as far as I can tell, is that the incentive structures aren’t there. Maximizing learning just isn’t a priority for most schools.

For this new breed of software though, they’re selling to parents, at fairly high prices. Some parents really care about their kids actually learning, and so the incentives are much more direct and aligned.

Does math academy still start at 4th grade? How do you compare it to beast academy or AoPS? What incredible results have you observed?

I hadn’t heard of Mentava, how does it compare to Lexia Core 5? I’m a little skeptical of claims like “my 2nd grader reads at a 4th grade level”. I’m privy to the standardized tests and I found the grading super inflated.

It is a bicycle for the mind, but the mind still sets the direction. Sometimes it's going faster towards a dumpster.

Here, let me revise that expression: "computers are ELECTRIC bicycles of the mind". You know this feeling, and we know it's how humans operate: when given a choice, we will ALL take the easy path. School is hard, learning is hard, and it all takes years and years of effort. Give a child a computer, or a smartphone, or AI, and all of a sudden, we don't have to expend any effort, like that electric bike. I shut my brain off and trust the ride, because it is effortless. Forget the part about having UNDERSTANDING of why things are true or false, why things work, how they work, how physics and mechanics and chemistry ALL are needed to create things. As an engineer (retired), I see youth having great KNOWLEDGE at their disposal, but feeble to no UNDERSTANDING of how things work, why they work, underlying mechanics, underlying theories, etc.

Ask any youth today about the smartphone in their pocket. Do they have any inkling of the decades of research and development for that device and it's capabilities to coalesce into what it is today? I mused once on some public forum about the inverse square law and how it applied to the fantastical ability of a smartphone to connect with a cell tower 5 miles away. The power received by the tower is approximately 3 times 10^-13 Watts or -95.15 dBm. This, to me is almost magical. Yet the forum members did not even know what the inverse square law was. They just ridiculed my comments and literally downvoted my musings to zero. I can't comprehend the ignorance of today's society.
