Duolingo can aid in your journey to become fluent, but if you aren't actively practicing the language with a native speaker or practicing your comprehension skills by listening to native conversations, then you will not become fluent. However, I wouldn't use Duolingo by itself.
Why is Duolingo not good?
But it introduces some really central problems: Translations are kind of boring to memorize, They're actually fairly hard to remember long term, Translating sentences is quite challenging work (there's a reason translation jobs are considered jobs rather than recreation activities), and most importantly…
What are the disadvantages of Duolingo?
- Its speech recognition software has a long way to go.
- Keeping up with constantly decaying skills can feel discouraging.
- Some of the translations are iffy.
- If you're serious about learning a language, Duolingo does NOT stand on its own.
Is Duolingo a waste of time?
It's a waste of time. In fact, it's just as bad as the education system Von Ahn criticizes. Duolingo outsources its translation services, allowing for awkward sentences to slip in undetected. And translation (the core of its platform) is already widely known to be an ineffective way to learn a language.
