Defining Levels of Global Tech and Economic Acceleration

In order to see if there is significant global and economic acceleration there needs to be a baseline to compare against. This is unambiguous technological wealth standard to measure world-changing effects. The other measurement would be to use quality goals related for measuring changes to quality of life. Unambiguous quality measures of change would be like enabling lifespan unaffected by any aging effects. Aging would be reversed and agings deaths would drop globally to 1% or less of the current levels.

The world has been roughly doubling its GDP in purchasing power parity (PPP) terms every 25 years.

The World GDP in PPP terms was
$26 trillion (2011 dollars) in 1970.
$54 trillion (2011 dollars) in 1995
$110 trillion (2011 dollars) in 2020.

The growth from 1950 to 1970 was faster at about 2.8X over 20 years. Going from $9.2 trillion to $26 trillion. This was the postwar boom.

The World GDP in PPP terms projected with 25-year doublings
$220 trillion (2011 dollars) in 2045.
$440 trillion (2011 dollars) in 2070
$880 trillion (2011 dollars) in 2095.
This is a rough baseline of a world without technological acceleration. It if roughly comparable to the rate of progress of the last 50 years.

A 1% higher annual growth rate over a 25-year cycle would be about 28% more growth for that cycle. Getting to a doubling beyond the baseline would mean 1% higher annual growth over 75-years or about 3% more growth annually over a 25-year cycle. A 50% boost in a 25-year cycle is matching a post-war boom. A globally significant lasting technological acceleration would go beyond the post-war boom.

Quantifying and Categorizing Global Technological Acceleration

Significantly moving the needle in terms of achieving globally significant technological acceleration would be the number of doublings beyond the baseline.

Level 1 (one global doubling) : $440 trillion PPP GDP by 2045 or $880 trillion by 2070 or $1760 trillion by 2095.
Level 2 acceleration (two doublings) $880 trillion by 2045, $1760 trillion by 2070 or $3520 trillion by 2095.
Level 3 acceleration (three doublings) $1760 trillion by 2045, $3520 trillion by 2070 or $7040 trillion by 2095.
Etc…

Being on track for Level 1 would be increasing the global GDP growth rate by 3% and forecasts showing this to be sustained for 25 or more years.
Being on track for Level 2 would be increasing the global GDP growth rate by 6% and forecasts showing this to be sustained for 25 or more years.
Being on track for Level 3 would be increasing the global GDP growth rate by 9% and forecasts showing this to be sustained for 25 or more years.
