Just look at this video recorded only in 2013 and see how relaxed people were back then. Okay, I'm not defending that image either, but now everything is so serious. Did you get into YC? Are you a Harvard graduate? Do you have a PhD in AI? Do you have amazing traction? No? Then get out.

Probably, this is a natural evolution that ends up in a "mass media" phenomenon, and we need to find a new space or branch that is different and more realistic (for the benefit of the market AND the people).
IMHO, startups are ill-defined (e.g. "infinite" scaling) and the use of "life-style business" is derogatory if we try to define a startup that doesn't want to scale at inifinitum or is wise to wait for the real opportunity. I always use the example of Nintendo, or even Intel. Nintendo started selling playing cards and Intel business were RAM memories.
I would say, like in a Zen koan [1], that we need "alternative startups" or "underground startup culture" more than "indy startups". It sounds weird because the use of "alternative" and "underground" is against a system but startups are in the system but koans are good for thinking on this.
