I use OpenMediaVault to run something similar. It’s a headless Debian distribution with web based config. Takes a bit of work but I like it.

I wouldn’t say skill issue, more of time issue. You only get a week to implement something. Quicker to use existing libraries than try to optimise yourself.

I get your point but I disagree. I think both Tony Stark and Justin Hammer are more competent than Elon.

Hammer was no where near as good as Tony but he did make some good stuff.

I would say he’s more like Obadiah Stane, an opportunist taking credit for others work.
