Do we still need to put mobile/cell phones to airplane mode?

I have been wondering about this for a while and thought this is the right place to ask this with so many aviation experts.

Do we still need to put mobile/cell phones to airplane mode? I still do it every time before the take off to minimize any interference with radio, but I'm not sure if that's even the right reason for it.

My questions are:

  1. Why do we need to turn on the airplane mode?
  2. At what point it's most important to do so?- taxi, take off? Seems to me most communication happens before the actual take off stretch, so do we have to do this as soon as we sit down?
  3. So many people continue using their phones and no one really enforces it, so it's not that big a deal safety wise?
  4. Is there more recent technology that minimizes interference that this is not enforced at all?

Thank you for any information in part or full. I'm aware I'm sounding pretty naive at this point.
