It's incredibly fast, has the features you would want like tabs/splits, maintains comprehensive compatibility, and is written cleanly in Zig. What's not to like?
Most terminal emulators are in fact slow and they can be a huge bottleneck if you run complex TUIs or workloads that print a lot of output.
Ever written a program that was extremely slow only for it to run instantly after removing your debug print statements? That's because your terminal is slow.
Fast terminal emulators already exist, but they notably refused to add tabs/splits and overall tended to be quite janky. Ghostty merging these features may not be the most groundbreaking innovation, but a high quality piece of software that can drop-in replace something you use daily with some cool improvements is something to be excited about to me. :-)
I agree that many small businesses jump to Kube too early. If your entire app is a monolith and maybe a few supplementary services, then Kube is massive overkill.
But many people also tend to overlook all of the other benefits that suddenly become very easy to add when you already have Kube, such as a common way to collect logs and metrics, injecting instrumentation, autoscaling, automated certificate handling, automated DNS management, encrypting internal network traffic, deployment tools that practically works out of the box, and of course immutable declarative deployments.
Of course you can build all of this yourself, when you need it, but once you have the foundation up and running, it becomes quite easy to just add a helm chart and suddenly have a new capability.
In my opinion, when the company it big enough to need a dedicated ops team, then it's big enough to benefit from Kube.
