RSA is strong though?

  It is instantly (figuratively) broken by quantum computing, which is on the horizon. The industry is in the process of telling everyone to stop using old encryption schemes now - not later - and switch to "quantum-safe" methods instead, like lattice-based encryption. Why? Because of the concept of "store now decrypt later." It is speculated that entities are mass logging encrypted data of interest now, so that they can decrypt and review it as soon as quantum computers are available. Great Veritasium video on the topic: https://youtu.be/-UrdExQW0cs https://youtu.be/-UrdExQW0cs I personally think it is feasible that a quantum computer will exist with enough qubits (the algorithm already exists: Shor's Algorithm) to break all of our current encryption in around 5-10 years.
