There is a lot more subtlety to Technic. Pieces are smaller and there and there are more ways to connect them. Duplo is just sticking big blocks together. If you want to build anything more complex than a tower, you'll have to build it much bigger with Duplo than with technic.

The two systems are compatible though. So since Duplo is cheaper to build big things with, a Hybrid approach will probably be more efficient in many case.

All these things are also true for quantum computers and normal computers.

A computer is something that takes an input (like some button press), processes that input, and then gives you an output (like Mario jumping on a Goomba).

The processing is a mathematical problem that the computer has to solve. It does it by breaking the problem down into a whole bunch of very small problems: like the Lego of mathematics.

Some problems are easier to build out of these basic building blocks than others, and so there is a difference in how fast the computer can solve them.

Quantum computers use different building blocks to normal computers. They are like Lego Technic instead of Duplo. So they'll be able to solve problems that normal computers will struggle with.

My fellow quantum people don’t, because they are quantum too. Normal people also don’t, because it would be weird.

Probably not. They'll most likely be cloud based, so probably not responsive enough on those time scales.

The biggest I think is that people seem to think that even the inputs and outputs of quantum computers will be weird and quantum. They are just computers, and like any computer we will we feed them with our inane questions and need to receive understandable answers. It is only during the processing that the quantum magic happens.

So in a few years time, you may well be using packages that call on quantum functions, and never even realize it is happening. Quantum computing won't just be limited to people with PhDs.
