This kind of pointedly naive questioning -- starting the conversation over at zero -- is an extremely unhelpful "discussion" (debate) tactic, and is really annoying to boot.
"Disclaimer: At the time of writing, I don't have any kids of my own, and I have no firsthand knowledge about how to raise kids. Enjoy reading, though!"
Great! So I'm just off to write a blog post on how to produce gold from base metals. I have no firsthand knowledge about alchemy, but how hard can it be?
Except that it's not just 'a link' is it? It's billions of miles of copper, fibre optics, routers, switches, media converters, legal agreements, large buildings, nuclear power stations...
If only this were true. And yes, it's cutely naive and tunnel-visioned to think so. However, I've been in teams where the drag on the ticket was very much a developer. When that happens, you need processes and experienced people in place to fairly manage their performance, help them into contributing more effectively, and if they don't improve, get rid of them.
A gaggle of developers are not going to be able to do this. Hell, 50% don't even have the social skills to say hello to each other in the morning.
Or...you could very carefully hire the right people in the first place, people that are motivated to work on their own and believe in the mission of the company, and would be doing the same thing regardless.
Vetting hires for temperament and internal qualities as well as skills makes this much more possible.
No it's not. You're being reductive. Even self-motivated, driven, talented people have shit happen in their lives that can effect their performance and capability at work. Then they will require both formal and informal support from their company, which has a duty of care.
This nirvana of extreme self-motivation at all costs you seem to espouse is not a reality for most people on the planet. It is most likely a privilege.
Once you made your first million, you become an Angel investor of course, hacking the startup ecosysstem. :)
But you don't spend on cars or shit like that's just baggage. For every new item you own, you have to think of it, you have to worry about insurance, maintenance, cleaning cringe
I know a few people who, if not live exactly like this, certainly think like it.
Walling yourself off from all dependencies (physical, financial, emotional) in order to grow your brain and Just Write Code might seem like a smart thing to do, and the purism of it will appeal to some. If the OP genuinely obtains no enjoyment at all from anything else, then that's fine - that's what it sounds like.
But it's the pay-off that stings, the 'shit you don't need' attitude, which is ultimately judging everyone else as inferior for not making the same choice, or having the (immensely privileged?) ability to 'make your work your life'. I love and value my family & my friends, and spending money to spend time with them enriches my life.
I moan about work sometimes but I like work - I like the social interaction, social interaction needs people, people are sometimes dicks, dicks are something I moan about BUT overall I'm happier because I work despite occasional downsides.
