You can do that as a hobby, or you can do it as a startup but treat the startup as a 9-5. (Your leisurely pace of work might hurt your chances of staying ahead of your competitors, but that's only important if you want the wealth and fame part.)
In order for me to continue building something nobody has built, I need it to be generating revenue. And in order to generate revenue I need to stay ahead of the competition, which probably requires not treating it like a 9-5. So yes I'm pursuing money, but not to achieve vast personal wealth, but rather to ensure my (hopefully) novel business is long-term viable.
I disagree with this - I think it's very much a reflection of the modern world being quite focused on profits and revenue - you can build an exceedingly successful thing that doesn't provide a clear revenue stream. It won't come with the glamour that other options may have but if you look at passion projects from things like open source libraries all the way down to dwarf fortress it's quite possible to make a living building a thing - it just won't give you 200k+ in annual income.
There is a place for artisanal projects in the modern world - a lot of creative folks subsist greatly on patreon as a source of income.
That's more of a crapshoot though. The vast majority of open source projects don't generate enough donations to sustain even a single developer. The vast majority of indie games don't experience the success of Dwarf Fortress.
A clear revenue model from the beginning makes it much more likely that you will be either A. long-term sustainable or B. call it quits before too much time is invested.
I disagree with this - I would agree that most projects don't end up making serious bank but I've seen a pretty impressive diversity of things being represented on patreon and taking in enough expenses to easily cover overhead costs.
If you are working for fun on an artistic/creative endeavor then you'll often need to cut personal corners to keep a real job to keep the lights on but you can seek and receive funding to prevent that hobby from becoming too much of a cost sink. This is also starting from the fact that your goal isn't to build a megacorporation (at least I didn't read it that way) - you're looking for the freedom to build a thing you want to build. You absolutely will pay a personal cost for that freedom, but the internet is a pretty diverse place where I wouldn't be surprised if you could find people willing to subsidize your work.
Like most people pursuing a passion project, it's wise not to quit your day job and throw everything in the basket initially, but if it's something you want to pursue it you can find funding to help lessen the costs you'd otherwise need to pay out of pocket.
Ok, I guess for some founders keeping their business viable at all requires a very large commitment. I think that's going to depend on how saturated is the market you're entering, and various other factors. I still believe that most founders could work much less if they were not in pursuit of vast wealth/fame.
