I'd make sure a lot of people causing big trouble today wouldn't be able to cause that trouble if you catch my drift.

Do I have the power to change things on a large scale? Cuz like, I was already an adult by 2011, and I still just sorta watched as shit went to shit. I did 'my part', and I warned people when I could about alarming trends they were unwittingly contributing to, but no one cared, and to be honest, unless one can actually hit the powerful folks, there is very little an individual can do.

If I have power to change things, to actually affect the powerful people, then I'm going to Y2K and I have a few ideas:

• Stomp Jair Bolsonaro to death a full decade before he becomes popular. When he was a nobody state representative from São Paulo who was only there to generate more seats for his party.
• Arrange a convenient accident for Steve Jobs years before the iPod drops. People talk about technology becoming boring, I place the blame for that entirely at Apple's feet. And it all began with the iPod, which in turn, if you believe the stories told, was Jobs' baby, to the point he harrassed the engineers at Apple for years until it was EXACTLY as he had planned.
• Stop 9/11 from happening, which slows down the US's descent into being a Police State, which in turn slows down the rise of neoconservatism/neofascism pretty much everywhere. Oh it'll still happen, but maybe if it happens more slowly, there might be fewer victims and people might do something about it sooner.

Oh and

• "Disappear" Peter Thiel. People really sleep on how much damage Thiel has done because he doesn't post cringe as often as say, Musk. But he's the high priest for the techbro "we are building god" faith.

I can't exactly do much about Climate Change with the time given. For that I'd need the same power-scale but to go back to the 60s, when the first scientists took notice of the trend but had their research suppressed by big oil.

Build a multinational resistance of 'extremist terrorists' willing to kill and be arrested, team with Anonymous, and wait for Luigi Mangione to be ready to join us.

Because, as the US and UK governments would have us believe, the term 'terrorist' means someone who threatens not the lives of the innocent, but the possessions of the financially rich, morally corrupt and politically powerful.

Probably do everything in my power to ensure the gaming landscape isn't as predatory in terms of having to pay for online access on consoles and seeing the Devil itself ( big red N ) go down in flames. Also, try to make console exclusives seen as something nobody is interested in anymore and are unwilling to purchase, more or less towards the 2010s rather than the 2000s, otherwise some of my favorite franchises wouldn't exist.

XboxLive? Find a way to fudge all the numbers to make it look like absolutely nobody was buying it!

GameCube? Find a way to ensure little to no 3rd party devs make anything for it by any means possible!

PSN? Keep that free like it was for PS3!

Would need to spend months, if not years, to figure out how to make all of that and ending console exclusives a thing, but a world without all that, IMO, would be a better world.

Well if you allowed one more year, I really feel that stopping the Columbine shooting would have an exponential improvement on the quality of the timeline.

Diplomacy.

After 9/11, when the world weighed an invasion of Afghanistan, America could have skipped the invasion, taken the Al Qaeda leadership the Taliban offered up, and continued to seek O/UBL. A forensic investigation and specific arrests, extradition, trials, and convictions would have been much better than a disastrous 20 year war that accomplished two things: enriching military contractors and the impoverishment of a central Asian nation.

Diplomacy.

Deposing Saddam Hussein with the same type of pressure that, later, led to the ousters of Hosni Mubarak, Ben Ali, and Bashar al Assad. Some might say that 2003 created the pretext for the Arab Spring. I'd counter that time and tide created the conditions. Operation Iraqi Freedom was a pipe dream and an extension on the GWoT piggy bank.

Diplomacy.

Building a better, more sustainable future demands a move away from fossil fuels. Making driving, urban sprawl, warfare, agribiz, and Amazon packages into a socially toxic soup of ideas would have done wonders for green initiatives. Instead a turn away from the largest industries of the time was — and still is — regarded as heresy.

I'd call and write to every newspaper and law enforcement agency and report the perpetrators of 9/11 a couple of days before it happened. I'd also place a decent bet on it happening anyway

I'd pump the brakes on technology. Especially the internet.

"Does X need to be improved?" "No" "Then we don't progress it because its current state functions and does things as efficiently right now" "Does Y need to be improved?" "Yes" "Then we research, fund and progress it"

Phones would be fun again and not just a series of rectangles with silicone. They'd have any design that they want, so long as it still functions normally as a phone would.

• Do what I could to stop the passing of the SCOTUS Citizen's United ruling
• Write a letter to then Senator Obama that there's a major recession coming and that holding the banks accountable and buoying the lower and middle class is a better option than a bailout of the private sector
• Warn about various impending natural disasters around the world to try to save as many folks as I could

Convince a guy in Google to not publish a paper that started this AI nonsense.

Find Elon musk and tell him that only betas use ketamine, and real epic cyberlords smoke fent

I'm going to visit the Cincinnati Zoo in 2016 and stop this one kid kid from falling into a gorilla enclosure.

Edit: fixed spelling error

Be really obnoxious about the ballot format in the Florida 2000 election until they either fix it or news outlets do a good job educating people about how to correctly vote for Gore

Do I just get one shot or can I keep trying until I get it right?

Basically anything that reduces Republican power in the US is probably a win overall.

Pretty sure that's how we got here in the first place.

Considering I’d just be some guy, I’d invest all of my money in Nvidia and Bitcoin then when I get back and have millions, I’d spend it on passing wealth taxes and raising the minimum wage.

I would get everyone to sign the Paris agreement and give it real teeth for non compliance.

Prohibit social media.

The other half of states that do not have ballot initiatives should have them. So the drug war would have ended peacefully. Contaminated overdoses and corruption would have been prevented.
