They added this new heart system and now it sucks

They decided to add a system to make more money, the heart system. Im getting so fed up with this one little typo or I pick the wrong version of a word and bam 4 hours until my next heart and I either pay or earn the hearts which takes a very long time and takes away from learning a language because instead of learning the language and immersing yourself in the culture you stuck playing and playing to get more hearts or buying the very overpriced gems, overall if they dont change this Im done with duolingo.
