• Tailscale and its CEO Avery Pennarun: Avery Pennarun is the CEO and co-founder of Tailscale. A version of this post was presented at a company all-hands.
• The focus on the present vs. the future: Usually, they focus on what exists now and what's coming in the next few months. But more companies are buying Tailscale for its future potential.
• Looking back to the start: David Crawshaw's first post was about "Remembering the LAN" from the 1990s. Many at Tailscale remember doing LANs, which gives them an age gap compared to other startups.
• The pros and cons of being "old": Being old means not being able to do long coding binges like in the past but having enough experience to do things right the first time. It also means seeing the tech cycle and patterns.
• What went wrong with modern computing: Programmers today are too focused on scaling and forget that most things don't need to scale. This has led to a lot of complex and inefficient systems.
• The Internet and its problems: The Internet has made networking hard. Things that used to be simple, like logging and orchestration, have become complicated. Tailscale is building a new OSI layer 3 to avoid these problems.
• The pendulum swing: The tech industry has gone from centralized (IBM) to distributed (Microsoft) and now back to centralized (cloud + phone). We have a giant centralized computer system with a few megaproviders.
• Operating systems and HTTPS: In the 1990s, operating systems mattered. Now, javascript and HTTPS control connectivity. HTTPS is a centralized system with a client and a server.
• Taildrop as an example: Taildrop shows how Tailscale makes things 10 times easier. It's a simple HTTP PUT operation that bypasses firewalls and doesn't cost money like traditional file transfer methods.
• The need for everyone to have Tailscale: There will be a new world of haves and have-nots. If not enough people have Tailscale, no one will build apps that work in a post-Tailscale world.
• The company strategy: Tailscale gives away the product for free and focuses on getting it into enterprises. Their goal is to have everyone in the world using Tailscale.

In summary, Tailscale is building a new Internet to solve the problems of modern computing. It started with a focus on the present but is now aiming for global adoption. Taildrop is an example of what's possible with Tailscale, and the company is working hard to make it accessible to everyone.
