Thanks for pointing this out. I didn't question the 10k hours at all.

Can I ask you what your background is in programming/computer science?

Well now put in 10h a day and you are an expert in half the time. Now also consider that languages are quite similar to each other and you could become an expert in less than 10k hours. So she being an expert in more than 2 languages doesn't sound so unreasonable anymore, right?

I also know devs who make that kind of money, but they are the exception not the norm.

I have already watched that video and 10k hours is not that much. That's just 5h a day for 5.5 years. I also can immediately recognize undefined behavior in C++, and I have at most 2 years of experience. Let me tell you for someone who has been programming for more than a decade, all the languages are the same. It's not hard to become an expert in a different langauge once you have the basics down.

Well on Wikipedia it states that she has been programming since 12.

People with these type of salaries are usually managers and don't really code that much anymore. I don't really get your point there. Also could you explain what an expert for you really is?

Here is her stackoverflow profile https://stackoverflow.com/users/2274694/lyndsey-scott

She has 37k points there, this fact alone already makes her stand out. And yes she does have a specialization. It's iOS Development.

Also it's bullshit that experts only know one or two languages.
