Do you think the era of scrappy startups is over?

I listened today to a podcast about the future of startups. The overall idea was that startups that hurry to launch without providing a quality product and differentiators, will most likely fail.

I'm also in a pretty competitive niche, so I would have to agree with what I heard on the podcast. Providing a high quality product and focusing on the customers should be our first priorities as founders.

What do you guys think? What's your approach on this?
