After reading Matt Shumer’s “Something Big is Coming” yesterday, which has hit 55M views, I started searching high and low for any and all counter arguments. Not because I believed he wasn’t being honest. Or revealing valid a tectonic shift coming. But because there is always two sides (minimum) to every story. Not sometimes. All times. Forming opinions based on one side is how you get lobotomies becoming accepted psychiatric practice for twenty years. So, is there any other viewpoint other than the end of the world as we know it where we’re all noodling at the local lake for our dinner? Perhaps. And, if so, this is the best I’ve seen. Take a deep breath. And read it. You’ll take a deep breath after reading it, too.

I've accepted that tonight is going to completely break me emotionally, or it'll be the best sports night of my life with nothing in between. I'm terrified.

Doctor: “do you have any pre-existing heart conditions?” Me: “yes, the Mariners are currently in the playoffs.”

Even if you don't care one bit about scientific research, it's important to recognise the value of publicly funding people working on very hard problems and training bright young minds on how to solve them. Do you think it’s a coincidence that so many successful entrepreneurs have a science background? The US didn’t become a global leader in technology and innovation by accident. It got there through decades of public investment in science, building research groups where young people could throw themselves at the toughest questions we face. Today, 49% of US unicorn CEOs hold STEM degrees, and 70% of founding teams include at least one person with a STEM background. That pipeline of innovation was forged in universities and national labs, not in boardrooms And when research is sustainably funded, the best international students come to US universities, and stay to build their companies (Elon Musk is one of them). Over 50% of international students in the U.S. are in STEM fields. Do you think this will continue if their research funding collapses by >70% and they can be kicked out at any time because the current government picks a fight with their University? In the 21st century, attracting smart young people is the most valuable resource any nation can have today. In the future it will become even more critical. Scientific research is one of the strongest magnets for talent. You can ignore it, but the US is dismantling one of its most powerful engines of innovation

The Vatican has the chance to do the funniest thing...
I was excited to hear that President Trump is open to the idea of being the next Pope. This would truly be a dark horse candidate, but I would ask the papal conclave and Catholic faithful to keep an open mind about this possibility!   The first Pope-U.S. President combination has many upsides. Watching for white smoke…. Trump MMXXVIII!
