10 Things in Tech: Renting properties to sublet them, the world’s largest polymer 3D printer, and a bare-bones Tesla Cybertruck interior

Happy Memorial Day, mates. I'm Diamond Naga Siu, and I'm excited that the French Open main draw is in full swing today.

I'd love to watch it in-person someday. But flying to France is super expensive (especially from San Diego).

So maybe I'll try this flight hack — called skiplagging — that airlines hate. My colleague Taylor Rains breaks down how this hack legitimately finds you a cheaper flight. But it runs the risk of you getting banned from the airline.

Maybe it's worth it to see my favorite tennis players compete on clay.

Before I try skiplagging, let's dive into today's tech.

1. ChatGPT helped these people earn more money and become better at their jobs. Many people are using ChatGPT to level up their work. Insider profiled four of them about how it has made their jobs easier: a recruiter, broker, entrepreneur, and chief marketing officer.

• They each use the technology for different aspects of their roles. One of them likened the technology to "having a 24/7 assistant." Another uses ChatGPT as their chief technology officer.
• They each took us behind the scenes of how ChatGPT helps with their specific tasks. But the common thread among their experiences is how much time ChatGPT saves them.
• My colleague Jack Sommers gathered their profiles and highlighted how these workers turbocharged their jobs with technology.

4. ChatGPT is a "black swan event." These rare events occur when something unforeseen happens with far-reaching impacts — but in hindsight, it looked inevitable. Many signs (like how ChatGPT blew up Big Tech) point to it qualifying. Check them all out here.

5. This couple rents properties to sublet them on platforms like Airbnb. Nathan and Taniera Turner turned to this side hustle after both got laid off at the start of the pandemic. Now, they've scaled up to 25 different properties. Here's how they did it.

7. The bare-bones Tesla Cybertruck interior. We might just have gotten a first look inside the Tesla Cybertruck. Photos — allegedly from a shareholder day — began circulating online. And the interior is shockingly minimalistic. Drive over to check it out here.

8. $20,000 doesn't go far for a car. Around five years ago, 60% of used cars were under $20,000. Now, only around 30% of used cars are under that pricepoint. Hop in to see the full used car landscape here.

Odds and ends:

9. The world's largest polymer 3D printer. It's like a massive glue gun with hundreds of settings. The gigantic device (60-feet long and 10-feet tall) helped print a 600-square foot tiny home in Maine. Tour the structure here, btw. Then, get a full, 360-look at the printer here.
