Old Earth Technology brought back

In recent readings I've had, the messengers have mentioned that humans are about to rediscover an old world technology that humans who were aligned with Earth used to use...that was put away on purpose...and I'm supposed to remember how to use this from a past life to help humans now...have you ever heard of this? Do you have any insight? 

Thank you for your time and messages, I'm grateful for finding you.  Much peace and many blessings to you and your family 💓
