Startups are "Overrated". What do you think?

My concern is if you are building it to ACTUALLY, solve a problem you're passionate about, OR You just want the "Cool" that comes with it! I strongly believe that at least over 60% of us, consciously or unconsciously, do it because it is "cool". Cool to showcase "Series-XYZ" on LinkedIn, and putting "Founder" on social profiles.
