I understand whence this comes and why it sounds appealing but if Tesla meant that human science can prove and harness metaphysical to aid the physical, I have my doubts (or it's so far out into the future as to be irrelevant). My thoughts on science stem from one of my favorite quotes that Neale Donald Walsch channeled from God. "Do not waste the precious moments of this, your present reality, seeking to unveil all of life's secrets. Those secrets are a secret for a reason. Grant your God the benefit of the doubt."

Here's my philosophy of modern science. Broadly stated, I think too many scientists waste time and money on matters that are undiscoverable and or have no practical impact on improving life; and too many resources are used to develop technology that is used so we can acquire things eaiser and faster that don’t actually contribute to contentment. https://medium.com/know-thyself-heal-thyself/technology-versus-soul-1ff8121a7e8c
