You wanna fuck up the timeline? Somehow mess something up so plastic was never, and never will be invented. That would change sooooo many things.

Id show up at the time travelers convention.

I often wonder how people would react if you showed up to a concert hall in, say, classical music era Europe or something and performed modern music. Assuming you could kit it to provide infrastructure for whatever your performance required, and the acoustics of the venue were idealized.

Would attendees hate it? Would the unfamiliar musical styles be repulsive to them? Would the sounds and textures of modern instrumentation like electric guitar and synthesizer upset or even frighten them? Or would they find something to appreciate about it? Would the music be copied and spread, becoming a time worn classic folk tune in an alternate future? Or would it be rebuked and suppressed, condemned for all time as evil influence? Which genres would have the best acceptance chances in which cultures, and which eras?

In my mind in particular, I think about this with the niche realm of video game soundtracks. If not just the music played as-is through some playback device (which would probably be rather boring, but who knows, maybe the novelty of recorded music alone would be fascinating enough) then perhaps arranged for live performance, like the orchestral performance of Undertale, or the Sinnohvation big band album. Or, of course, if the soundtrack was itself a recorded live performance, just perform it. These collections of compositions often outline rich adventures, communicated by a wide range of musical styles. I wonder if they are strong enough to stand alone, and if audiences would respond to them without the context that they were written to accompany.

Failing live performance (which would be trickier than one would think–to sound good, live music has to be written with its venue in mind, and I’d assume most modern music would sound like garbage when performed in victorian era concert halls or ancient ampitheaters), I’d also consider putting them to vinyl LPs and dumping them in old record shops in any era that had phonograph or turntable technology and see if they get discovered.

Why not just send back the video games themselves? I dunno. I guess I’m less interested in wowing them with futuristic technology and more interested in how they’d react to something they already have (music), but in a strange, new context.

I’d save RFK and give him a full two-term presidency. Just because I’ve always wondered how much a difference it would have made in the course of American history. It definitely seems like things took a severe turn for the worse in the late 60s and the American political system has never recovered.

I personally believe there were conspiracies to assassinate both him and JFK because they were not susceptible to being controlled by their donors or political mentors, as is the case with the vast majority of politicians. They were rogue elements with a strong potential to disrupt the status quo (i.e. gravy train) for the rest of the oligarchy, so they got taken out.

I wonder how much difference one Stinger SAM would have made at Blair Mountain in 1921.

I’d prevent the Challenger launch. Manned spaceflight doesn’t get shelved for an entire generation, and a young me doesn’t lose hope for the future at such an early age.

Through a bizarre series of butterfly effects, the successful launch and its international attention gives bureaucrats in Pripyat an extra nudge to encourage cooperation amongst their engineers and nuclear scientists, and a critical flaw in the operation of the plant at Chernobyl is caught before it causes a catastrophic meltdown.

The cumulative effect is a continued culture of progressive technological expansion into the 90s, and the fading of the anti-intellectualism that threatened to overtake the world during the Reagan and Thatcher administrations. Hand in hand with this is a decreased militarism, as technology is increasingly seen as a tool for the betterment of humanity, and less as a means of building better weapons.

One other immediate result is in the US presidential election of 1988. A lack of meaningful engagement with the public (no “skipped the surly bonds of earth” speech) led to increasing apathy toward the outgoing Reagan administration, giving G.H.W. Bush a tougher hill to climb, and less solid footing on the issue of defense. Dukakis doesn’t feel the need to do a silly photo op in a tank, but instead campaigns partly on an expansion of the space program and educational outreach programs similar to the one that brought in Christa McAuliffe.

Neoconservatism and neoliberalism wither together on the vine. Permanent human presence in space continues uninterrupted for the next two decades, with a base on the moon by the end of the century and a manned mission to Mars planned for a decade after that.

No Bushes, no rise of Al-Qaeda in 1988, no Gulf War, no Rush Limbaugh, no Clinton’s, and no 9/11.

If you’re fine with utterly erasing pretty much every human being conceived after that point in favor of new human beings (or other creatures entirely) may as well go big or go home and start here.
