You're not being an ass. This is a question we struggle to answer every day. (I'd argue that even very successful companies have to struggle to answer it every day if they want to remain successful.)
I think that there are two separate issues here. The first is that many of these lessons came from messing things up with RethinkDB. RethinkDB didn't germinate this way at all -- many of the things we had to fix, and many things we can't fix so we have to live with their consequences daily. These lessons aren't right for everyone (and you can't hit the ballpark on all of them no matter how hard you try), but if I started another company, this is what I'd look out for and strive for. If you want to do something different (like open a dive shop in the Caribbean), that's awesome (really -- I mean that; I always feel a bit of envy for people who take this path). It's just not what I would do if I started another company.
As for RethinkDB augmenting the human condition, this is a lot simpler than it seems. Thousands of people take time out of their day to learn Rethink and build cool things on top of it. In many cases RethinkDB is crucial to their livelihoods (because their products depend on Rethink working). Instead of spending their time on thing X, they spend it on Rethink, which gives everyone here a tremendous sense of joy. Since the adoption is growing extremely rapidly, it's giving us a great platform to reach more people. We have lots of things in mind that will allow people to do things they can't feasibly do today. That's augmenting the human condition.
(You can't look too far out. We're not inventing flying cars, but if we can make scalable web apps accessible to people that couldn't do it before, well, that's augmenting the human condition for them.)
In that context that's a perfectly reasonable piece of advice. Without an "enormous potential for growth" you're likely not going to get substantial interest from investors or have the kind of outcome that folks joining your "startup" would expect.
If that's the case then your critique is off-point. He was deliberately excluding the those kinds of businesses from his analysis.
I think the author is describing the vision a startup should have, even before it starts tackling the problem its trying to solve.
Using your coffeeshop example, if the owner's goal is to, one day, change the way people drink their coffee (in a better way that the owner believes), then yes, this vision is worth pursing, and he/she might need to start out as a corner cafe at first. If the owner's goal is to have his/her own corner cafe and have a stable income from it, then its not a startup.
But, as you said, "a huge number of people" and "augment the human condition in a meaningful way" is pretty vague wording, but the intend/meaning of his statement seems reasonable to me.
i think @beachstartup's point is that the problem with treating this as a "lesson" is that you're imposing a value judgment on other peoples' value creation by saying that what they're doing, possibly their LIFE'S WORK, is NOT WORTH DOING just because they may not "augment the human condition for a huge number of people in a meaningful way".
For example, any failed venture could probably be said "not to augment the human condition for a huge number of people in a meaningful way". Goodbye scientists who are trying to cure cancer but haven't succeeded yet. No offense, patio11, but bingo cards? Come on... try to augment the human condition a bit.
It just comes off as judgmental and moralistic bs.
1. Getting to ramen profitability with a team of 2 – 4 within six months to a year, AND
2. augmenting the human condition for a huge number of people in a meaningful way.
Well shit... if SV is a community of 2-4 person creating profitable products that augment the human condition every year...
"augment the human condition", "a huge number of people", and "a meaningful way" are really subjective and arguably VERY few people are doing things that meet those criteria.
those criteria aren't offensive, but the part that flips me was "it's not worth doing". Granted its 4 words in an otherwise insightful piece, but I have a problem with it when people tell others that their life's work is worthless.
People pursue all sorts of activities in their lives, personal and professional, that, by this metric aren't worth doing.
i'm aware, of course, that you've written opinionated pieces that narrowly define "startup" as well, so maybe all those things just aren't startups and don't apply.
but of course this (i believe false) line of reasoning then raises the question of what tiny business couldn't be considered to be potentially an augmenter of the "human condition for a huge number of people", doesn't it?
this is the kind of arrogance i find disheartening about these kinds of lists. really - things aren't worth doing unless they clear this impossibly ambitious bar?
should i tell the owner of the corner cafe i stop into after work every other day, and that gives me a huge amount of joy nearly every time, that she should give it up because her business doesn't "augment the human condition for a huge number of people"? how about the guy who wrote the $5 clipboard app that makes my life much easier? i'm sure he has lots of customers but "a huge number" that have "augmented" their humanity because of his clipboards....
and i hate to be an ass, but ... under whose criteria does rethinkdb qualify for this, anyway? how meta do we have to go here? how many degrees of separation are we talking about exactly?
the problem with these kinds of statements is they can be rationalized by smart people into all sorts of justifications for doing and/or not doing a huge number of things.
