And are we sure that it is working or it will get cracked in 10 years by a guy with laptop and Python?

Whole cryptography often time feels like snakes oil. You can't tell if algorithm you are using is not actually fundamentally broken. Or we know that algorithm is fundamentally broken (like RSA) and we are just one mathematical discovery from a digital catastrophe.

Take a Dan Boneh cryptographic course and learn something rather than espouse FUD whataboutisms.

Actually this is reality of cryptography. Is AES secure? Well lot of people tried to break it and failed. Which does not answer the question because we don't have any mathematical tools to say yes this cryptography algorithm is formally verified to be secure and unbreakable. It can turn out that tomorrow we will find a flaw in AES which will make it leak key after capturing few blocks.

Only thing which we know is unbreakable is OTP and that's because it is easy to prove it.
