Yes, you're right.
I think trying to forecast the future will always be a challenge. We have jobs appearing and disappearing. Most of the tools we have to try to make projections are based on the past. We use data from the past to try to forecast the future. Right now that's the best we can do.
We know that jobs will sometimes not exist in the future. We're not sure what the jobs will be five years from now. Jobs are changing all the time, as new technology appears and older technology disappears.
That will always be a challenge. It's clear we will have to develop better tools and try to figure out what other tools we could use to identify the jobs of the future.
