The Magic DNS feature is super cool as well. I'm not sure exactly what the mainstream killer app would be. But I feel like Tailscale is poised to execute if/when it arises.
Perhaps the AI age makes everyone more data privacy conscious.
I've also long thought that eventually every household will eventually have a mini server for home automation and storing personal information. The rise of the cloud kinda slowed this down, but I don't think cloud and home server are mutually exclusive.
Agree that they are on to something. I gave a tech talk about them a while ago at work and said that I think they are on the cusp of providing a consumer VPN product that appeals to mainstream consumers. The Apple of VPNs, everything "just works" and is easy to understand.
I've always been a big fan of KDL in principle, haven't used it in anger. After that HCL, then YAML, with JSON and others being my least favourite to use.
Of course the hard part is gaining enough critical mass to make a significant switch. JSON had AJAX. YAML had Rails. What could make JSON5 or KDL break out?
