I don’t think nushell or crush for that matter copy PowerShell. They have learnt from MS and built upon what they didn’t get right. Strongly typed objects on the command line is theoretically interesting, but slow and complex in practice (why does it still take 3-4 seconds to run ls / gci in my homedir at home?). Text in columns gives you the simplicity of text coupled with some level of structure.
No. Its acceeptable, and mostly startup related. Certainly not even close to the level u claim. Once started it is more or less OK depending on specific cmdlet and task in question. I use it in production on numerious gov level services serving millions.
Vim is slower for example but rarelly anybody compalain about it given its power.
