I.e. building a game is great, but if they have to "code" for days before they see something happen then they loose interest (assumption). So preparing "building blocks" might be a good approach and have them first implement higher level stuff and then step by step dig deeper and implement the building blocks you prepared.

You program drone in Erlang of course :-)

Pretend :-)  )  Notice how they - fluidly - bounce across languages, massacring every grammar rule ever, but quite happily making sure that you understand that "I amn't going to eat pea, ನಾನು ತಿನ್ನಲ್ಲ, ನಾನು ತಿನ್ನಲ್ಲ, odio odio odio la piselli, i don't wanna, where is my red truck?"

That's a bit of a challenge considering that Erlang is created to solve problems that are rather "industrial" and most people "from outside" can't really relate to. If the audience is not comfortable with understanding the problem itself then it is tricky to make them understand/like the solution too.

So they often just go off and eagerly try to solve all sort of issues they are familiar with (even when they are not relevant in the particular case) before even trying to understand what the real challenge is. Then they start complaining that Erlang is not very good for some/many of those issues they are busy with.

"Installing applications can lead to corruption over time. Applications gradually write over each other's libraries, partial upgrades occur, user and system errors happen, and minute changes may be unnoticeable and difficult to fix"
