In the context as in this question, I'd go for a gender-neutral option - see Alicja Fajfer's answer.

All in all, the Anglosaxon part of the world should be happy as they are not aware of all the issues and problems resulting from the masculinum/femininum/neuter gender-related grammar (and political correctness!) questions that we have to cope each and every day in our Slavic part of the world.

In the US and the English world, in general, one avoids the "he/she" choice by using the plural "they." In Polish it is easy to change the ending of verbs to achieve the same purpose. (Actually, some people have begun to use "they" as a singular, gender-neutral pronoun. We will see how far that goes.)

Dziękuję Michale za agree, ale zdecydowałem, że moja odpowiedź dużo nie dodała.

Sam, if you're not afraid of potentially offending a proportion of the female audience who will watch the video, go ahead and use the masculine. :)

Thanks, Maciek. Just wondering exactly what would be properly spoken by a narrator (as opposed to what would be customary to see in printed form)... Sounds like the consensus is to simply use the masculine form. I don't know Polish, so this questions comes from a position of complete ignorance. :)

@Maciek: Also a good possiblity

Sam, do you want to avoid a double masculine/feminine form? If so, I'd just say 'Czy czasem marzysz, by nauczyć się programowania?' or something along these lines.
