My first thought: Look, this is Cuba. Home of con artistry. They will stage a UFO landing to get more tourists spend convertible pesos. For me P(heard-in-havana-and-true) is around 0.1, max.
Funny, this could be extended to all sorts of investments. What if I spent 1000 USD on Apple in 1990? I'd have about 1000 Apple stock now, currently worth around 160k.

I don't know about this particular software, but I'm not too sure about this whole "giving my kid an advantage in life early on" business.
I think there was a study done [1] that showed that love and security and the availability of parents and family mixed with a certain degree of freedom were more crucial to success later in life than skills such as math. It allowed children to explore the world on their own, but if anything bad happened they could always rely on parents to be there for them. To tell them things would be fine, or to put a band-aid on their wounds. This allows children to develop trust in others, self-confidence and a positive outlook in life. While at the same time motivating them to explore the world.
However, another very important thing was allowing the kids to join in when the family (or other kids) were solving a problem. This could be anything from helping with cooking, fixing something in the house or collecting firewood. I assume the benefit of this was not only practice of problem-solving and social skills, but also allowing them to develop a sense of self-worth.
(The problem is, I guess, that our modern world is solving all our problems for us. We don't repair, we replace. We buy solutions for things that we'd had better dealt with ourselves. And so forth. And that we put so much emphasis on self-reliance, which seems to be a good thing but in reality has serious disadvantages. I believe this is one of the big (root-) problems of our modern civilisation that nobody seems to be talking about, but I might be wrong.)
Furthermore, the ability to work on a specific problem _with others_ is a different from being able to do maths alone. It teaches all the right things in life.
So I guess the point is: If you want your kid to succeed, be there for and allow it to take part in life the way he or she choses to (all within reasonable limits of course, you still need raise your kids to be decent etc.), especially with others.
