As has been mentioned in here, the "Talent Shortage" was made up to get an increase in H1B visa workers to drive down wages and get more for their money. It has always been about flooding the developer job market. Case in point are the interviews at many big tech companies that require leetcode/algorithms interviews. Companies are ready to reject any candidate that makes even a small mistake on one of their solutions, or misses the exact optimal solution. If they really needed top talent and couldn't find it, they wouldn't be so careless in their hiring rejections. Another issue is also that its really difficult to quickly shift tech stacks on a dime. As much as people like to claim it to be possible, even just upgrading from Hadoop/MapReduce/Older big data technologies to Apache Spark is a massive time investment. The paradigms are the same, the technology when used in practice is different. Workers can see their whole knowledge base become useless in the span of two years. As an individual worker, if this happens three times in 8 years, I think burnout would be expected. Anyone who is capable of constantly updating their technology knowledge to a T is probably already CTO of a company somewhere. Maintaining the ability to memorize and understand inane minutia over a few decades span is rare, and is probably coupled with severe disabilities in other areas of life.
