Hot take: defund any space research outside geostationary orbit and move these resources to fixing Earth. Really, we don't need to know if there were bacteria on Mars 2 billion years ago, we need more green tech, more monitoring of Earth systems and an attempt at carbon scrubbing.
The entire advanced mathematics. Go sufficiently far and mundane matrix multiplication will look like daemonic sigils. Write out a moderately complex math proof and you're essentially commanding inhuman tongue. Then when you convince them that it's really not devil summon spell you can tell the old era folks, that all these symbols is why the sun rises as fast as it does and moon has phases.
In 10 years time Musk or someone like him will be sending sun dimming space umbrellas to "fix global warming"
Did research on oobe advance past Monroe or are we still operating on vibes and "trust me bro"-based meditation techniques?
True, but there are way better fammade 5e implementations of the MtG worlds. Not sure if they already got to Capenna, but I've seen Kamigawa and Innistrad and honestly stuff looks like WotC made it themselves. Will post links when I find them tomorrow
(of course alongside defunding 75% of the military)
