If bitcoin was created in such a way that it could never be hacked does it mean most of the btc is lost forever cause from my research i found that 50% of btc have been lost and can never be recovered isn't that a scary prosect that majority of the btc goes untouched maybe for like a thousand years till maybe future generations finally access it but by then it would be worthless so in truth only a very few get to benefit from it just like most things that have value in this world.
No one can prove that the bitcoins are lost forever except those coins that were sent to the cremation address. You can read some details here
https://en.bitcoin.it/wiki/Proof_of_burnThe idea is that miners should show proof that they burned some coins - that is, sent them to a verifiably unspendable address. This is expensive from their individual point of view, just like proof of work; but it consumes no resources other than the burned underlying asset. To date, all proof of burn cryptocurrencies work by burning proof-of-work-mined cryptocurrencies, so the ultimate source of scarcity remains the proof-of-work-mined "fuel".

the ~196 BTC lost people tend to keep forgetting about at every nice milestoneOther than these bitcoins and some bugs that some blocks weren't mined in the early days of Bitcoin, all coins that are claimed to be missing are a claim and may one day be reached.
The rest of the bitcoins that have not been moved since they were mined or years ago (including coins mined by Satoshi) are reported as lost but no one can guarantee that.
In the future, with the development of quantum computers, it is possible to recover some of the old bitcoins, or those that were used in the early days, and the file was deleted (if file recovery techniques develop).
