Global government debt on course to hit 100% of GDP by 2029 – how will this play out?

i heard this research today and its been boggling my mind, mainly because there has been an upgrade in livelihood for the people in the current day, like i hear that wealth inequality is the highest yet i have to admit the quality of life is drastically better. over the course of the 100 years we have discovered new technology, new advances in science that have created an impact on how we function day to day.

what am i wishing to know how will this realistically play out? will society collapse in itself or has there been a new bedrock achieved in the height of technological advancement that a new order would be formed? where the modern era of technology continues and but the pivotal factor of money is removed?
