Need of the hour to change existing encryption to be quantum resistant


I would like to highlight the fact that recent quantum computer developments may be edging closer to cracking many common encryption methods and ending public encryption as we know it today. Therefore, I urgently appeal to the Tor project to make quantum-resistant encryption, as current quantum computers are getting ever so close to cracking public encryption, and I think we need to acknowledge this change.
If we start now, we may be well in time for Q-day.

Thanking everyone,


How close?
Can they crack artificially weakened encryption today?
For example, with lower key length.
