Quantum - is it really that dangerous? No...

Hi, I used to work as a technical full-stack developer and recently I spent some time investigating this thing everyone's talking about "Quantum computing destroying encryption". Well, there are many remedies already available:

Example 1 - for not technical people: https://www.nist.gov/news-events/news/2024/08/nist-releases-first-3-finalized-post-quantum-encryption-standards

Example 2 - for technical people: https://github.com/open-quantum-safe/oqs-provider

Most companies / IT projects are not prioritising it only because quantum computing threads might be decades away, and businesses don't execute investments on security unless there is a true threat. That's why your email providers, messaging apps, etc. don't have post-quantum standards implemented (such as: ml-dsa, ml-kem, slh-dsa).

Yes. It is more complicated to secure decentralized Crypto than a website, but - anyway most of us use platforms like CoinBase, Kraken, Binance, .. and those holding crypto in one-single physical wallet - are not really the targets here.

Anyhow, please, I hope my post helps some of you to be a bit calmer about this topic. I am definitely calmer after my research. Let's not cause panic sell-off.

Have a great day everyone!
