For people who program for leisure, self-consumption or otherwise don't have a major income pressure, it is objectively a huge time saver.

I've had much enjoyment recreating my frequently used utilities on macOS. It's not about saving money, it's costing me more than to keep my subscriptions active, it's more about tailoring things to myself and keeping BPMs up.

There's nothing that will save your employment time because any employer will want to maximize what they get from you. This applies to literally any innovation past, present and future.

A personal anecdote from 2 decades ago which hunts me till today.

I was at a smallish firm in NYC, less than 50 people. I ran the "IT department" which included a couple of devs, DTP folks and one customer support underling who I backed up when needed.

We fixed all the printer problems, all the network shares, everything was quiet. I get called into the corner office and am told, "tell the help desk dude to sweep the floors as they are not doing anything". And, I really liked that boss. It's a different mindset.
