Maslow's Hierarchy of Needs is still very accurate and relevant in 2021

I believe survival's Rule of Threes provides a more accurate framework.

Here’s the Rule of Threes in a nutshell, After which we’ll go into it in depth:

3 seconds – time of useful consciousness due to explosive decompression in a vacuum
3 minutes – time of useful consciousness for an athlete in top physical condition without air; you begin to succumb to hypothermia if plunged into icy seawater
3 hours – you can succumb to hypothermia on land
3 days – you die without water
3 weeks – you die without food
3 months – you die without adequate nutrition
3 years – you’ll give up without other humans

While Maslow does excel with respect to recognizing the human need for self-actualization, Many self-actualized individuals, Myself included, Would argue this involves achieving a measure of continued success while moving beyond their own survival needs. Thus, Having and taking care of one's family, Neighbors and local and national community fully meets Maslow's multiple definitions.
