OK, this comment was not really helpful. The article described some really interesting tech. Trashing tech or people who are excited by it does not really make things better.
Not only is that not really relevant, but I'd argue Tailscale is actually very useful even to many people who don't feel like they currently "need" it.
I can understand Oxide (though current vmware apocalypse might make their appeal bigger than expected), but Tailscale?
Tailscale's biggest proposition is that their VPN software is, arguably, the easiest I've ever managed. There systems that are better integrated in some environments, systems that provide various niche features, etc.
