5 Essential Reads on AI, the Conversations Teams Are Losing, and Leading While Depleted
Every month brings a flood of new research, talks, and reports on leadership and team building … and almost no time to actually read them. So each month we cut through the noise and gather a handful of the most useful, credible, and thought-provoking pieces for leaders at mid to large organizations.
This month: Microsoft Research on why AI’s gains stubbornly refuse to scale from individuals to teams, a peer-reviewed study in Administrative Sciences on the casual conversations hybrid work quietly strips out, CNBC on the executive burnout nobody at the top wants to name, Angela Duckworth at HBR’s Leadership Summit on why grit matters more in the AI era, and MIT Sloan Management Review on a practical way to defuse team friction before it hardens.
Here are five pieces worth your time, and what each one means for the teams you lead.
1. AI is a brilliant individual contributor and a mediocre teammate
Microsoft Research’s New Future of Work report synthesizes large-scale data analysis, field studies, and lab experiments to assess how AI is actually landing inside organizations, and its most consequential finding for leaders is one of distribution: the benefits are real but deeply uneven. AI still works far better for individuals than for groups. A team using it can underperform a single person with the same tools, because the handoffs, review steps, and shared understanding that hold collaborative work together were never redesigned around it. The gains do not scale on their own — someone has to redesign the workflow.
Why it matters: Rolling AI out person by person and expecting team-level results is how organizations gain individual speed and lose collective output.
2. The conversations you stopped having are the ones that were holding the team together
If AI has strained the connections between people, this peer-reviewed study identifies exactly which connections are load-bearing. Looking past the where of hybrid work to the how, the researchers examined daily informal communication — the unscheduled, low-stakes exchanges that happen when people are simply in proximity. They found that these casual conversations are precisely what drive knowledge sharing and organizational commitment, and that teams which deliberately recreate those touchpoints sustain markedly stronger cohesion and loyalty than teams relying on formal meetings alone. The informal layer is not social overhead; it is infrastructure.
Why it matters: The incidental conversations hybrid work removes were doing real work — recreate them on purpose, or watch cohesion and commitment quietly erode.
3. The burnout at the top that nobody wants to name
Rebuilding that connective tissue falls to your leaders — which is why this May 2026 CNBC report is such uncomfortable reading. Drawing on management experts, it documents a surge in burnout at the top of the house, where senior leaders now report stress, exhaustion, and isolation at rates rivalling or exceeding their teams. The piece is particularly good on why this goes unaddressed: the more senior the leader, the fewer safe places they have to admit depletion, and the more likely they are to read it as a personal failing rather than an organizational signal. What the business loses is the steadiness and energy their teams draw motivation from.
Why it matters: A depleted leader cannot fuel a motivated team, which makes executive burnout a performance issue rather than a private one.
4. Grit is back on the leadership job description
So what does leading well look like when the ground keeps moving? In this special episode from HBR’s Leadership Summit 2026, University of Pennsylvania psychologist Angela Duckworth makes the case that her long-standing research on grit — the blend of passion and perseverance toward long-term goals — matters more in the age of generative AI, not less. She unpacks how leaders can cultivate persistence and a growth mindset in their teams when the sheer pace of change tempts people to either give up or coast. Her argument is that character, not capability, is increasingly what separates strong teams from the rest.
Why it matters: As AI churns the ground beneath your teams, modelling grit and a growth mindset becomes a core part of the leadership job rather than a nice-to-have.
5. Give the friction a name and it becomes solvable
Sustained pressure of this kind tends to surface as interpersonal friction, which is where this July 2026 MIT Sloan Management Review piece earns its place. Ina Toegel and Jean-Louis Barsoux argue that whether team members collaborate well depends less on natural compatibility than on their capacity to work through and capitalize on their differences. They describe a facilitated approach in which a team completes a “Big Five” personality assessment, then uses structured discussion to connect its collective traits to the tensions it keeps running into. The effect is to turn vague irritation into a shared, workable diagnosis rather than a quiet source of blame.
Why it matters: When team friction has a name and a shared framework, it becomes a problem the team can solve together instead of a personality clash it learns to live with.

The thread that ties it together
Read together, these five pieces describe one problem from five angles. AI has made individual work dramatically faster, and in doing so it has put real strain on everything that happens between people — shared context, informal knowledge, trust, the ordinary work of keeping a group pointed in the same direction. Microsoft Research shows those gains do not scale on their own, and the Administrative Sciences study names the specific conversations we quietly stopped having. Rebuilding that layer is leadership work, and CNBC explains why the people responsible for it may have little left in the tank.
The encouraging part is that none of it requires new technology. It requires deliberate attention to how your people actually work together, and the energy for your leaders to give it. That is the work we do at Summit Team Building — creating the conditions in which teams reconnect, rebuild trust, and remember how to operate as a group rather than a collection of fast individuals. If any of this sounds like your organization right now, we’d love to talk.
