The next useful consulting wedge is not a smarter assistant. It is a narrow agent that owns one business function, operates inside constraints, and leaves a receipt after every action.
Personal agents will be most useful when they cross the artificial boundary between life and work. The hard problem is not keeping those worlds separate forever. It is building portable privacy contracts, minimal disclosure, and user-controlled memory into the agent itself.
Hardening an agent toolchain assumes you can predict every threat. Mature teams are adding instrumentation instead: decoy MCP tripwires, recurring sandbox escape research, acquisition audits, and empirical blast-radius measurement.
Human-facing pages will not be enough when buying, searching, and workflow decisions are increasingly delegated to software agents.
