A lot of people posting that they successfully recover their funds for along time but how about those who have lost their Bitcoin?
Only possible if they have hint to help the brute-force progress. Without any hint, it is impossible to do that successfully and brute-force private key or mnemonic seed is impossible if you have to start it from 0 with all seed words, all characters.
Is it possible in the future that there will be a technology that is specialized in recovering lost in just a matter of minutes or an hour?
If that happen, all bitcoin will have zero value because such technology will help to not only recover lost bitcoin wallets but also can brute-force all bitcoin wallets. What you own even with private key, mnemonic seed will be no longer belong to you.
The saying "Not your keys, not your coins" will no longer be true!
