You're talking about two different things. "Technology" in the phrase "don't be seduced by the technology" means, the tech used to
build your product. Not the technology of your product itself. Obviously you should innovate when making your product itself, but the
tools used to make the product don't need to be bleeding edge for you to do that.
E.g. if you make a website, it should be a unique and engaging website. But you can make a unique and engaging website with Java. Even though it's old tech, your users will not know or care.
