Your comment adds nothing of significant value. It's basically a "Me Too!" without offering evidence, extrapolation, enhancement or enlightenment.
I've looked at your profile to see if I could provide this feedback in person, without down-voting you, but there are no contact details. That's fine, but it's why I've left you this comment so you understand my reasoning. I often wish people would explain their down-votes on my comments, so I've done so here.
I've also noticed that you're new here. This is a somewhat harsh welcome, but I do look forward to seeing your viewpoints and ideas. I hope you've read the guidelines:
