I'm a bit cautious about this prediction. When the web became popular, I was convinced it would be the end of Estate Agents (Real Estate brokers) and Recruitment Agents. But both have thrived in an online world and seem as numerous today as they've ever been. Other automated changes for manual jobs would require substantial changes to infrastructure. For example, refuse collection using underground tubes to suck away rubbish is already a reality (e.g. Envac system designed in Sweden) but it's unlikely to be retro-fitted to existing housing developments. On the other hand, things like housing construction and crop picking I can imagine will continue to see improvements in automation.
