Yesterday, I woke up in the future.
A man, with a private company, has sent a rocket to space and left a car in orbit. It's truly the stuff of wild science fiction.
I was just 6 weeks old when a man stepped on the moon, and a teenager when I watched Challenger explode on TV. Since then, Space travel has seemed unobtainable again, a rare few launched from the steppes of Kazakhstan.
Today, it is a different prospect. Millions of words will be written about Elon Musk and his ambition to reach Mars, he'll fit it in alongside electric cars, solving power issues with batteries and shooting people from London to New York in less than 60 minutes inside a tube.
As well as the (not) flamethrowers.
What is really interesting is the horizon of these goals. Like Bill Gates, Jeff Bezos and Mark Zuckerberg, Elon Musk is working on stuff that possibly won't be fully formed and realised for decades.
Maybe not even in their lifetimes.
Like the work of Steve Jobs, who fashioned Apple into the earning machine it has become, earning more and more, even after his death. All of these leaders and their teams will be well rewarded this year and next year, and their families will never want for anything. Their companies and shareholders make huge amounts of money. Their products and services change lives around the world.
Most importantly though, their ideas and achievements will live on long after they have gone, these people are building dynasties from technology.
Their work will leave a legacy for many years.
