Maybe I can try to answer.
The labour shortage is really in every sector of the economy, and every type of professional work or type of worker. As an example, in Canada, one of the biggest issues in terms of the shortage of labour is people who work in technology. Technology is booming. There is a big demand for technology services. We don't have enough people to work in technology.
As regards the idea of investing in technology, technology doesn't replace people, but it could replace tasks. It could be a complicated task or it could be a more simple task. For example, you can buy software today to make reservations in a restaurant. It doesn't replace a person, but it does replace a task that a person can do.
The solution is really complex, because it really depends on every business model, but the issue is here to stay. That's what we are saying to our clients: You need to have a strategy, because it's not going to go away. The strategy is different for every business and every sector.
