Now they have -8 years.
Doc Brown actually went back and caused this invention to cease to exist, along with self-lacing shoes, the food hydrator, and the Mr. Fusion, in order to divert the timeline away from a looming nuclear apocalypse in the year 2045.
This is a thing that really happened... in a short released with the 30th Anniversary Blu-Ray box set.
physics matters.
no it doesn't
So, 2016 didn't have hover boards but they got the ubiquity of flat screen tvs correct.
This will be real in 2015 (😱)
We went from the first ever flight in 1903, to putting a man on the moon in 1969. I don't know at what point the advances stopped, but I guess people thought they'd just keep going
What? In our lives we have decoded the entire human genome. Half a million people live today that wouldn't if cancer research stopped.
The internet was created and literally connected the entire world and almost all its knowledge together.
You have a computer in your pocket that would have been the size of Texas 4 decades ago -- Transistor tech growth alone is absolutely remarkable.
Now, GPT4/AI has made it so ANY human with an internet connection can have access to a world class tutor on any subject. Think about the 150 million Indians that live below the UN poverty line and the opportunities that provides them and thus enriches the world's potential outputs.
If you want a read on how the world isn't actually getting as bad we as all read about, in totality, (I think our western institutions being corrupted and dying is another story), read this book -- https://www.amazon.com/Enlightenment-Now-Science-Humanism-Progress/dp/0525427570
While accurate, if feels disingenuous to frame it like this. Don't misunderstand me, I'm not disputing the rapid increase in technology following the industrial revolution, but there were many incremental advances over the centuries before that led to those moments. We didn't just begin to do things in the air in the 1900s.
As early as 969 or as late as 1264 rocketry was used to propel things through the air.
The dating of the invention of the first rocket, otherwise known as the gunpowder propelled fire arrow, is disputed. The History of Song attributes the invention to two different people at different times, Feng Zhisheng in 969 and Tang Fu in 1000. However Joseph Needham argues that rockets could not have existed before the 12th century, since the gunpowder formulas listed in the Wujing Zongyao are not suitable as rocket propellant.
Rockets may have been used as early as 1232, when reports appeared describing fire arrows and 'iron pots' that could be heard for 5 leagues (25 km, or 15 miles) when they exploded upon impact, causing devastation for a radius of 600 meters (2,000 feet), apparently due to shrapnel. A "flying fire-lance" that had re-usable barrels was also mentioned to have been used by the Jin dynasty (1115–1234). Rockets are recorded to have been used by the Song navy in a military exercise dated to 1245. Internal-combustion rocket propulsion is mentioned in a reference to 1264, recording that the 'ground-rat,' a type of firework, had frightened the Empress-Mother Gongsheng at a feast held in her honor by her son the Emperor Lizong.
In 1783 we were able to manage what I would call air travel. Flight is a bit of a loaded term but I think most would agree that this is flight despite being lighter than air.
The first untethered manned hot air balloon flight was performed by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes on November 21, 1783, in Paris, France
In 1849 a heavier than air glider was invented. Pinning this down seems tricky. There are multiple accounts of folks earlier doing it. I think the problem is where do you draw the line between jumping while holding "wings" and actually gliding. Regardless, this predates 1903.
The first heavier-than-air (i.e. non-balloon) man-carrying aircraft that were based on published scientific principles were Sir George Cayley's series of gliders which achieved brief wing-borne hops from around 1849.
Framing it as flight in 1903 to the moon in 1969 ignores a significant chunk of the histories of both air travel and rocketry.
Honestly, the smartphones feel like the last big innovation we've had. What's really changed since smartphones have settled into what they are now? What new technology has had such an impact on the world?
I don't know, feels like the world has settled for a while and that we're not doing anything cool anymore, especially as the internet falls into the corporate soulless garbage it's becoming.
Maybe the Artemis program will instill that sense of progress back into us.
I guess it depends on where the line is drawn. I think you're right though. The "ubiquity of smartphones" (as I call it) happened around 2015 or so. It's hard to pin down when it happened since it is intentionally a fuzzy definition. At some point smart phones became cheap enough that even kids were getting them. I didn't get my first on until 2010 or 2011 when I was in college. Even then a lot of folks still had "dumb" phones.
What's wild is hearing what people use smart phones for. My wife does fan fiction. Some pretty prolific writers in their mid twenties (so the oldest of gen Z I guess you'd say) have said they exclusively write their fics on their smart phones. That's insane to me.
Yea, ezplains all hte grqmmar qnd spelling errors
After the wright bros built that shitty airplane, we spent the next 60 years or so improving and making them safer, cheaper, etc. That's what's happening now with the internet and smartphones and things like that.
It's so early. In 2026, Ecommerce is expected to account for 1/5th of all sales. In 3 years, brick and mortar business will still have 75% share of sales versus online. We have a long way to go -- I think it's confusing because you're always living on the 'cusp' of tech and our lives are so slow and short compared to reading about the last 150 years or whatever
Let's compare NASA engineer's salary to a engineer at Raytheon or Boeing's.
A lot of people that could have been rocket scientists went to work for wall street.
To be fair, we can still invent the hoverboard by 2015.
We just need to invent a time machine to go along with it.
I'm over here riding my self balancing electric unicycle going 30mph 15 miles from my house thinking to myself that the future already kinda rules
Didn't hacksmith on YouTube actually make one?

Heck yeah!
When they manage to build a working hover board, the real challenge will be that it must not work on water. 😉
Omg is a fucking joke, why are people taking these so seriously?? 😂
Just because it's a meme doesn't mean we can't discuss it more seriously in the comments.
This has always been functionally impossible at the current understanding of science, even with superconductors. There's nothing to "push off of", unless you can invent literal anti-gravity technology, which afaik, is impossible.
Sure, the Earth has a magnetic field, but it can barely move a compass needle. It can't even lift a single gram of weight, much less some dude and a board.
You need a rocket in the bottom to be able to fly around freely. Or you'd be limited to keeping it inside a special area made just for it, using electromagnets.
Just replace all roads, sidewalks, and building interior floors with magnets. Easy.
