but the main idea I've caught is that if Bitcoin doesn't implement post-quantum algorithms, it won't survive until 2027.

If you read a bit more around, for example the Bitcoin wiki, you'll find out some interesting facts and predictions from people that understand Bitcoin and cryptography. For example that it's not so easy to "break Bitcoin" even with quantum computer.
I will add 2 interesting quotes from the wiki:

Quote

Bitcoin already has some built-in quantum resistance. If you only use Bitcoin addresses one time, which has always been the recommended practice, then your ECDSA public key is only ever revealed at the one time that you spend bitcoins sent to each address. A quantum computer would need to be able to break your key in the short time between when your transaction is first sent and when it gets into a block. It will likely be decades after a quantum computer first breaks a Bitcoin key before quantum computers become this fast.

Quote

A sufficiently large quantum computer would cause some trouble for Bitcoin, though it would certainly not be insurmountable.

Thank you for informing me about that. I was thinking what could happen when quantum computer will be real thing what could happen to Bitcoin holders, but after I read these two short quotes I am more safer to hold my money in Bitcoin than ever. When quantum computer start stealing information from traditional banks, my holdings will remain safe behind cryptography code, which is really good to know.

Sentence "Bitcoin will die at 2027." is completely BS.
