Sadly since couple of years or so ago we forgot about UX. Or quality in general. I have a companion which tells me I did everything right before pushing to prod. WCGW
If you want to learn a language you are supposed to feel emotions. I speak OK English now (not my mother tongue obv.) and I still remember the silly mistakes I made while I was playing online games 10-12 years ago and people made fun of me. Never made those mistakes again.
Now I am learning a 3rd language in a new country. I started with Duolingo and never believed in "Paid courses". I have used it close to a year with little impact on my skills. But I have made most of my progress when I actually talked to someone. There is a feeling of embarrassment and defenselessness when you put yourself in uncomfortable situations like that and that is what you need to make it stay.
