For more than a year, Silicon Valley techies have abandoned their homeland and poured into Miami in search of startup El Dorado. As Candy Cheng reports, the influx of newcomers is causing friction with the locals. 

• A Founders Fund VC who moved to Miami in April declared the start of the inaugural "Miami Tech Week," never thinking that there already was a Miami Tech Week.
• "These folks are saying they 'discovered' Miami, which to us is frustrating," said Brian Breslin, a longtime figure in the city's tech scene, comparing the newcomers' attitudes to "Columbus coming and claiming he discovered America."
• If you're in Miami, here are some of the hotspots where newcomers and longtime locals network and make deals.

If not Miami, then space. There's another group of brash Silicon Valley adventurers setting off for new horizons, and lucky for them, where they're going there are no locals to clash with (we think). 

• Amazon founder Jeff Bezos announced that he and his brother Mark will be on-board the first rocket from his Blue Origin company to blast into space, on July 20.
• Blue Origin's New Shepard rocket is completely automated and will provide passengers three minutes of weightless bliss in space before returning to Earth.
• There's one seat left on Bezos' spaceship, and the auction to buy the ticket closes on Saturday (as of Thursday, the bidding had reached $4 million). You may recall that Bezos once promised to reserve a seat on his rocket to send Donald Trump into space — could there be a surprise bid from Mar-a-Lago? 

Meanwhile, rival space entrepreneur Sir Richard Branson may try to beat Bezos to orbit by blasting off in a Virgin Galactic spaceship on July 4.

Elon Musk, the other space race billionaire, has yet to announce plans for his own imminent trip. But chatter has centered on a prediction from a 1953 book that describes a leader called "Elon" leading humans to Mars— seriously.

And a former Blue Origin employee has just raised $650 million to build 3D-printed rockets. 

Even Palantir, the data analysis company, has a spacebound employee. Kelli Gerardi 32-year old Tik Tok star and logistics expert at Palantir, will be aboard a separate Virgin Galactic flight expected to launch in 2022.

"Less than a thousand humans have ever been to space — fewer than 100 women, only a handful of moms — and my 3-year-old is going to watch her mommy become one of them," Gerardi told Insider.

Insider asked dozens of top VCs to name the most promising Startups of 2021. They were asked to nominate startups they had invested in as well as ones where they had no financial ties. And they delivered an exciting list of companies, across all stages from newly launched to unicorns, each thriving for different reasons.

In our first on a series of stories of the Most Promising Startups of 2021, we present a list of 46, many of whom were named by multiple VCs as being companies to watch this year.

Yesterday's innovative breakthrough is today's retro tchotchke, and the miniaturized version of Polaroid's classic instant camera is a fun, and instructive, reminder of the olden times.

The tiny plastic Polaroid Go spits out photos that gradually, over a period of 10 to 15 minutes, develop all by themselves. Once upon a time, that was a big deal — it meant you didn't have to take your film to be developed at a shop and then wait a couple of days to get prints of your photos.

For today's digital generation, there's nothing special about being able to view pictures right away, of course. 

But perhaps the Polaroid has something better than mere nostalgia to offer Gen Z.

Scarcity is an increasingly foreign concept to those living in a time of super-low interest rates, bottomless social media feeds, on-demand streaming movies, and smartphone cameras that take infinite selfies. With a film camera — even a toy-like instant camera — you only get a finite number of pictures. Each shot needs to count. Imagine that.
