While the technologies we’d most desire, including:
* instantaneous teleportation,
* safe travel through a wormhole,
* or warp drive,
would all be transformative, they seem to require something that doesn’t exist within this Universe, at least as we understand it today.

Around 1850, James Clark Maxwell postulated all of those in his 200 field equations. All but 4 were thrown out by a self-educated man who lived in his mom’s basement and never revisited again.
Today, Maxwell is little known, and his original manuscript is near impossible to find.
He’s only remembered for his contributions to electrical theory. Where 4 field equations were turned into vector equations by the the self-educated man, giving us all we know about the electromagnetic spectrum - which covers pretty much everything. Neither Einstein nor Tesla would have amounted to anything without reading Maxwell first.
“Today, Maxwell is little known”
He is hardly little known. Every student of physics, at any level beond high school, knows about the 4 Maxwell equations.
I am assuming you are talking about Faraday.
