The Biggest Problem In Digital Infrastructure Isn’t Technology - It’s People

Recently, we had Tony Rossabi on The Route to Networking podcast with Jamie Maher discussing everything from telecom evolution and AI infrastructure to data center growth and the future of digital infrastructure.

After the conversation, we explored some of the technology and infrastructure side of those discussions further in The Telecom Industry Never Stops Changing - And That’s Exactly Why People Stay In It, where we looked at how telecom has continuously reinvented itself through every major infrastructure shift over the last two decades, from voice and fiber to hyperscalers and AI.

But the more we reflected on the episode afterwards, the more it felt like another theme kept quietly surfacing underneath all of the conversations around growth, AI, and infrastructure scale.

People.

Because despite all the focus on technology right now, Tony repeatedly came back to the same point throughout the discussion: none of this growth happens without skilled people behind it.

The more he spoke about hiring challenges, operational pressure, leadership, and the pace of infrastructure expansion, the more it felt like the industry may be approaching a point where talent itself becomes one of the biggest constraints to growth.

That’s what led us into this article.

After hearing Tony’s perspective throughout the episode, we wanted to dig deeper into why talent, adaptability, leadership, and people development may end up becoming just as important to the future of digital infrastructure as the technology itself.

The Industry Is Growing Faster Than The Workforce Behind It

Throughout the conversation, Tony repeatedly spoke about how quickly infrastructure demand is accelerating, particularly across AI infrastructure and data centers.

At one stage, he said:

“We’ve seen more growth in the data center space in the last 18 months than probably the last 15 years.” 

That level of growth creates enormous pressure across the industry. More facilities are being built, more power is being consumed, and deployment timelines are becoming increasingly aggressive as businesses race to keep up with AI demand.

But while infrastructure growth is accelerating rapidly, the workforce behind it doesn’t appear to be scaling at the same pace.

Tony spoke very openly about that challenge during the episode:

“We can’t train people fast enough.” 

That statement probably carries more weight than people initially realize because infrastructure industries don’t scale in the same way software businesses do.

Behind every data center, network expansion, or AI deployment are huge numbers of people responsible for designing, building, operating, and maintaining that infrastructure. Engineers, electricians, operators, project teams, construction specialists, network architects, and leadership teams all sit underneath the technology itself.

And listening to Tony throughout the discussion, it became increasingly clear that talent shortages are no longer just recruitment problems. They’re becoming operational problems too.

Technology Still Depends On People

One thing Tony repeatedly emphasized throughout the episode was how easy it is for the industry to become overly focused on technology itself while forgetting the people operating behind it.

At one point, he said very directly:

“You cannot operate technology without people.” 

That sounds obvious on the surface, but it feels increasingly important right now as conversations around AI and automation dominate the industry.

Because while AI may automate certain tasks, it also creates entirely new infrastructure demands at the same time. More compute requires more facilities, more cooling, more connectivity, more operational support, and ultimately more skilled people capable of managing increasingly complex environments.

That was one of the more interesting themes running underneath the entire discussion. The more advanced infrastructure becomes, the more valuable experienced people often become alongside it.

And according to Tony, businesses are already starting to feel the pressure of competing for highly specialized skillsets across multiple areas simultaneously. Data centers, fiber, networking, cloud infrastructure, AI infrastructure, and power are all growing aggressively at the same time, while often pulling talent from the same limited pool of experienced professionals.

The Industry Has A Knowledge Gap Problem Too

Another interesting part of the discussion was how often Tony referenced learning and knowledge transfer.

Not simply learning new technologies, but helping newer professionals understand the industry itself.

Digital infrastructure has expanded so quickly over the last decade that many businesses are now trying to scale faster than experience can realistically be passed down. Entire segments of the industry have grown massively in relatively short periods of time, creating situations where newer professionals are stepping into highly complex environments without years of historical operational knowledge behind them.

That challenge becomes even more difficult when the technology itself is changing rapidly at the same time.

Tony referenced this directly while discussing newer operational demands around AI infrastructure and liquid cooling:

“People are really learning about it… I’m not sure everybody fully understands it.” 

That probably applies across much of digital infrastructure right now.

Even experienced operators are adapting in real time because many of these infrastructure requirements simply didn’t exist at this scale only a few years ago.

And that’s probably why curiosity and continuous learning kept surfacing so naturally throughout the conversation. Standing still for too long in industries evolving this quickly can quickly become a disadvantage.

The Best Infrastructure Leaders Usually Sound Grounded

One thing that stood out throughout the episode was how grounded Tony sounded when discussing leadership and career growth.

A lot of conversations around technology leadership can become heavily focused on disruption, innovation, or future predictions. But Tony repeatedly returned to much more practical traits like resilience, organization, communication, adaptability, and confidence.

At one point, he made a particularly interesting distinction:

“There’s a difference between cockiness and confidence.” 

That line probably applies across almost every area of infrastructure leadership.

Because digital infrastructure industries are complex enough to humble people very quickly. Markets shift constantly, technologies evolve faster than businesses expect, and operational challenges rarely unfold exactly as planned.

The leaders who seem to last longest are usually the ones capable of staying adaptable when those situations happen rather than assuming they’ll avoid them entirely.

Tony also spoke honestly about the realities of working inside infrastructure industries:

“If anybody goes into some job… thinking everything’s going to be smooth, they’re sorely mistaken.” 

That honesty actually made the conversation feel far more grounded.

Especially because digital infrastructure often gets discussed almost entirely through the lens of explosive growth right now. But underneath that growth are still difficult deployments, operational pressure, staffing shortages, customer expectations, and constantly changing technologies.

The industry is growing quickly, but it’s still incredibly demanding.

Relationships Still Matter More Than People Think

Another thing that naturally came through during the episode was how relationship-driven infrastructure industries still are.

Despite all the technology involved, telecom and digital infrastructure remain heavily built around trust, reputation, and long-term relationships.

Throughout the conversation, Tony referenced people he’d worked with across different stages of his career, whether customers, partners, operators, or industry peers. And it became pretty obvious that many of those long-term relationships had played a major role in helping him navigate different parts of the industry over time.

That probably reflects the nature of infrastructure itself.

These are long-cycle industries involving major investments, complex deployments, and long operational timelines. Businesses want to work with people they trust because the projects themselves often become long-term commitments.

And as the industry continues accelerating, those relationships may actually become even more valuable rather than less.

The Industry Needs To Make Infrastructure Careers More Visible

One thing this conversation also highlighted is how little visibility many people still have into infrastructure careers altogether.

Outside the industry, most people probably don’t fully realize how much digital infrastructure supports everyday life, how many career opportunities exist inside it, or how quickly the market itself is growing.

And that becomes a challenge when infrastructure demand is accelerating this quickly.

Because if younger professionals don’t understand the opportunities available across networking, telecom, fiber, cloud, AI infrastructure, and data centers, the talent pipeline naturally becomes smaller over time.

That’s probably why conversations like this matter.

Not just because they discuss technology, but because they give people visibility into the industries, careers, and individuals behind it all.

And listening to Tony throughout the episode, one thing became increasingly clear: despite all the conversations around AI and automation, digital infrastructure is still fundamentally a people business.

Conclusion

After listening back to the conversation with Tony Rossabi, one thing became increasingly clear.

The biggest challenge facing digital infrastructure over the next decade may not simply be technology.

It may be people.

Because while AI, cloud, fiber, and data center growth continue accelerating rapidly, the industry still depends entirely on skilled professionals capable of building, operating, scaling, and supporting that infrastructure successfully.

That was probably the strongest theme running underneath the entire episode.

Technology matters enormously. But the people behind it still matter just as much.

And as infrastructure markets continue evolving, the businesses investing most heavily into talent, leadership, learning, and adaptability may ultimately be the ones best positioned for long-term success.
