If you want to play the long game and collect a lot of encrypted data now, you can simply wait until it is possible to trivially decrypt, and/or start cracking now and let the years work on it.

Most encryption decisions are framed as a tradeoff of the time and resources it would currently take to brute-force your way through it, and how many years before a simple attack becomes feasible, vs. your $5 wrench attacks in the present day.
