Big consulting firms are betting that AI will soon handle the straightforward tasks that have long formed the backbone of their billable hours. This shift puts a premium on skills that machines cannot replicate, and many firm leaders believe those skills are developed face-to-face, not through a screen.
The intersection of AI and remote work creates a direct financial threat for any business that bills by the hour. If AI tools allow consultants to finish projects faster, firms log fewer billable hours. If clients demand lower rates because the work requires less human effort, per-hour revenue drops. The result is a squeeze on both volume and price.
The interpersonal skills gap
Consulting leaders are now saying that future success will depend on what cannot be easily automated: interpersonal skills. Their assumption is that AI will keep absorbing the analytical and procedural work, leaving relationship-building, persuasion, and nuanced judgment as the differentiators.
Remote work, in their view, undermines exactly those skills. New hires learn by watching colleagues navigate client calls, handle pushback, and read a room. In virtual meetings, cameras are often off. Some participants send an AI agent to take notes rather than attend. The observational learning that junior consultants relied on disappears.
The consulting business model amplifies this problem. Firms have traditionally operated on a learn-by-doing apprenticeship system. A new hire shadows a supervisor who might be only a year ahead, watches how a task is done, then does it themselves. The model is cheap because the learner produces billable work while training. But it only functions when people are in the same room.
Bringing employees back to teach the next generation
The proposed fix is straightforward: rein in remote work and bring employees together more often. The employees who already have the skills and feel they can work productively from home are the same ones who need to be present so others can watch them. That tension makes the return-to-office push particularly difficult to sell.
There is a caveat. Learning by watching has always had a built-in flaw: it is hard to know which behaviors to copy. Many managers with years of experience are still bad at managing. A new hire observing a supervisor for the first time cannot easily separate good practice from bad. The worst violations of social norms stand out, but good supervisors sometimes make unpopular decisions that look wrong to an observer. Calibrating that judgment takes more than exposure.
Training as an alternative path
One outcome of the remote work era is that it made the value of interpersonal skills more visible. Some large consulting firms are now providing formal training and coaching on these skills rather than relying solely on osmosis. The assumption that interpersonal skills can only be learned in person is being tested, and structured development programs may prove faster and more reliable than the old apprenticeship model.
For HR leaders, this shift carries a clear implication. If AI handles more technical work, hiring and development priorities need to tilt toward the relational. The skills that keep people employed and firms profitable will be the ones that happen between people, not between a person and a machine. Resources on AI for Human Resources can help HR teams understand which roles are most affected and how to adjust workforce planning. HR managers looking to build internal capability can explore an AI Learning Path for HR Managers that addresses the intersection of automation and team development.
Why this matters for HR professionals
The consulting industry's response to AI is a leading indicator for other knowledge-work sectors. If firms that sell expertise are restructuring around interpersonal skills, HR teams in every industry should audit their own hiring criteria, performance reviews, and learning programs. The question is not whether AI will change the mix of skills your organization needs. It is whether you are building those skills through deliberate training or hoping they emerge from proximity. The firms that treat interpersonal effectiveness as a teachable competency, rather than a byproduct of office attendance, will adapt faster.
