You are truly oblivious, just blind to what exists in the world.
You're setting up an impossibly strict definition of a word whose definition is not widely agreed upon ("hacker"/"hacking"), then listing things that don't fall under the definition. Good for you. Bad for argument.
> Hacking started as an art, without regard for commerce
How far do you want to trace it back? 60's, 40's? How about a few hundred BC? Doing more with less, finding one's ways around limits has always been around and will always continue to be around.
Dipshit posers wiping their buddies hard drives will always be around, too. Does this make you happy? Is this what you want to be a part of? Would the world be a better place if we were all doing this?
> Writing software is now a team effort
WTF? Lots of stuff is a team effort. Lots of stuff is not a team effort. Don't join a team if you think it'll hold you back. What's your point?
Newton, "If I have seen further it is only by standing on the shoulders of giants." He was just some dilettante using the knowledge discovered and shared by the folks who came before him in a new and interesting way, I guess. Not much effort, there, just a bunch of cut-and-paste of existing code (ideas).
> having an corporate job or starting a Web 2.0 CRUD start-up makes you beholden to either your boss or your potential customers
And turning your computer on makes you beholden to Apple (or Lenovo, or Dell, or ...) and your power and data providers. It's turtles all the way down.
> van Gogh
Are you serious? Yes he did seek commercial approval of his art (Nuenen (1883–1885)) and yes he did choose colors based on what was popular and appearing in the museums of his time (Antwerp (1885–1886)). http://en.wikipedia.org/wiki/Vincent_van_Gogh
> the best art inspires, challenges and mocks the audience, but it never panders to its audience
[citation needed]. "Art" is a lot bigger than you're allowing for. Define it however you like. Put that definition in your wallet and show it to people at parties, but please don't assume your definition is bigger, better, or more perfect than everyone else's (says the little postmodernist living in my brain).
> Lack of Encouragement in the Community to Buck the Status Quo
Now you're taking the thing that defines the status quo--"Community"--and then complaining that it wants to follow what it defines? By definition, that's what the community does. Or do you mean that someone whom you believe should be encouraging you to do interesting things is not doing so? What, precisely, is it that "the community" owes you?
> early 90's at the dawn of personal computing
You mean almost 20 years after the introduction of the Apple II (in 1977)? Was that just pre-dawn? Early 90's already had Microsoft running more PCs than any other OS on the planet. That was pretty awesome for innovation and "anything's possible", huh?
> While occasionally Hacker News feature posts
Now you're just whining. If you want the HN scene to be more awesome for you then hang out, post more, and make it awesome. Otherwise, go back to your "real hacking is dead" sub-reddit and mope around there. This is what it is. Hacking is what it is. If your blinders prevent you from seeing awesome, take them off. You are info-rich and thought-poor, you are not entitled to have others filter the world in whatever way you want. If the community you find here isn't the community you want to be a part of, then run away like you're on fire.
> Where are the implementation of the next generation's ideas?
"Where's my flying car?" amiright? Implementations of "the next generation of ideas" are constantly fomenting. Many try, many fail. You've been reading too much futurist sci-fi.
> my commentary turned out to be still pretty liberal artsy
More "trolly" than liberal arts, I'd say.
