It reminds me of Y2K hysteria.
When old jobs die, new jobs arise. That has always been the case, and I haven't seen any evidence of that ending.
It also ignores a growing body of evidence.
If new jobs arise as you say in the same amounts, why is it that young people are having such a hard time finding gainful employment these days?
Take a look at the statistics, you'll find as some already have, that the job pool has been shrinking, and older workers who have more experience out-compete younger workers for entry level jobs because the cost to train (is high), and production is lower in workers with no experience than those with experience.
The only indicators we would have that this is happening, just like inflation, are lagging indicators.
By the time you know it is happening, its then too late to do anything. That's why this problem will probably kill us all. We as a species historically do not handle cascade failures well because we don't perceive the danger until its too late.
Its a problem where our natural biases work against us. Its normal to just discount problems we have no context, which is why the out-of-context problem is so dangerous.
Do you think the native people's of the Carribean thought there was danger from white sails of Columbus ships?
By what measure? Youth unemployment is right now around its lowest level in…quite a long time. [0]

BLS data has been manipulated and methodology changed to always paint the rosiest picture for policymakers.
The shadowstats website has continued with the older more accurate methodology where it shows a more realistic view, when it can.
US data for unemployment has been fundamentally flawed for decades. In essence, the methodology stops counting people looking for work when they have been unable to find work after some amount of time. If you aren't actively looking for work or recently had work, you aren't counted. Actively looking doesn't mean interviews, it means being registered in a work program, which has a large number of requirements and competition.
The resolution foundation has several good analysis of multiple countries that show this trend.
If you want more specific details than that, I'd suggest "The Pinch" by Willett. It has many credible references, supporting this at the back (too many to list).
Where other similarly themed books like "The Theft of a Decade", offer no more than opinion, this covers what you are looking for with gratuitous references.
There is nothing I can do about that.
The problem is that humans aren't getting specially smarter as generations go, but technology continue to grow
