The Telecom Industry Never Stops Changing - And That’s Exactly Why People Stay In It

Recently, we had Tony Rossabi, Co-Founder of OCOLO on The Route to Networking podcast with Jamie Maher to discuss his career across telecom, connectivity, fiber, and digital infrastructure.

What started as a conversation about Tony’s journey quickly became something much bigger.

The more we listened, the more it felt like the discussion wasn’t really just about telecom at all. It was about change. How industries evolve. How quickly technology moves. And how the people who build long careers in infrastructure are usually the ones most comfortable adapting alongside it.

After reflecting on the conversation afterwards, it also became clear just how many different versions of this industry Tony has experienced firsthand.

From the early days of voice over IP, through the rise of fiber and data centers, to today’s AI-driven infrastructure boom, his career has followed almost every major shift the sector has gone through over the last two decades.

And listening to him talk about those transitions made us think about something that probably doesn’t get discussed enough.

For all the talk around AI, hyperscalers, and next-generation infrastructure, telecom and digital infrastructure have always been industries built around constant reinvention.

• The technology changes.
• The companies change.
• The priorities change.
• The speed changes.

But the people who stay successful are usually the ones willing to evolve with it.

The “Cutting Edge” Always Changes

One of the most interesting parts of the conversation was hearing Tony reflect on what the industry looked like when he first entered it.

Today, most conversations around infrastructure naturally revolve around companies like Nvidia, Meta, Google, or hyperscalers building AI capacity at enormous scale.

But when Tony first moved into telecom in the late 1990s, the landscape looked completely different.

As he explained:

“The cutting edge companies were AT&T, Verizon and MCI… those are not the cutting edge companies anymore.” 

At the time, voice over IP was considered revolutionary technology.

Data center businesses barely existed in the form we know today.

And many of the companies now dominating infrastructure conversations were either tiny, struggling, or nonexistent.

Tony even joked that:

“Google was little… Meta didn’t exist… Apple was a nothing at that point.” 

That perspective probably says a lot about how dangerous it can be to assume today’s industry leaders will automatically dominate forever.

Infrastructure markets evolve constantly.

• New technologies create new demands.
• New demands create new companies.
• New companies reshape the industry again.

And according to Tony, that cycle is far from slowing down.

“In five years… we’ll probably have 10 or 15 new companies that will be revolutionary.” 

That feels especially relevant right now with AI accelerating infrastructure investment at a pace the industry hasn’t experienced before.

Telecom Didn’t Disappear - It Expanded Into Everything Else

One thing the conversation highlighted really well is that digital infrastructure didn’t suddenly appear overnight.

It evolved layer by layer.

Tony described how his own career naturally followed that progression.

• He started in voice.
• Then moved into transport and fiber.
• Then into data centers.

As he explained:

“What does fiber connect to? It connects to data centers.” 

That probably reflects the industry itself.

A lot of people still talk about telecom, fiber, cloud, AI infrastructure, and data centers as separate sectors.

But increasingly, they’re all part of the same ecosystem.

The video calls we take every day.
 Cloud applications.
 AI workloads.
 Streaming.
 Enterprise connectivity.

All of it relies on layers of infrastructure working together simultaneously.

Tony summarized that really simply during the episode:

“Everything is passing through somebody’s fiber, somebody’s data center, and potentially somebody’s tower.” 

And that interconnectedness is probably one reason the industry continues evolving so aggressively.

Because every new technology wave creates pressure somewhere else in the infrastructure chain.

AI increases compute demand.
Compute demand increases data center demand.
Data centers increase power demand.
Power limitations create new infrastructure challenges.

The entire system keeps expanding around itself.

The Industry Has Become Obsessed With Speed

Another major theme throughout the discussion was speed.

Not just technology moving quickly, but businesses demanding infrastructure faster than ever before.

Tony repeatedly came back to how dramatically priorities have shifted.

Historically, telecom businesses focused heavily on efficiency and cost.

Now, speed to market seems to be dominating almost every conversation.

As Tony put it:

“People are saying, ‘I don’t care about cost. I need speed to market.’” 

That probably captures where the industry currently sits better than almost anything else.

AI growth has accelerated infrastructure demand so aggressively that businesses are now prioritizing deployment speed above almost everything else.

And that pressure appears to be reshaping the entire market:

• faster deployment expectations 
• larger infrastructure builds 
• rising power demand 
• increasing pressure on capacity 
• more urgency around AI readiness 

Tony described the current situation in the data center market very bluntly:

“There’s almost no capacity.” 

And the scale of recent growth clearly surprised even people already inside the industry.

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

That’s a huge statement coming from someone who has already seen multiple waves of infrastructure transformation across telecom and digital infrastructure.

AI May Be Accelerating The Next Major Infrastructure Shift

AI naturally became a huge part of the discussion too.

And one thing that stood out was how Tony talked about AI less like a future trend and more like something already reshaping infrastructure markets in real time.

At one point, he mentioned speaking to a doctor who had recently visited MIT’s AI lab:

“He said, ‘I can’t believe what’s coming.’” 

That feeling probably sums up where a lot of the industry is right now.

There’s excitement around AI.
 But there’s also uncertainty around how infrastructure keeps pace with it.

Because while the conversation around AI often focuses on software or applications, the physical infrastructure underneath it is becoming impossible to ignore.

• Power.
• Cooling.
• Land.
• Capacity.
• Deployment speed.

All of those challenges are now becoming central infrastructure conversations.

Tony highlighted two issues that have remained constant throughout the data center industry:

“Finding reasonable space and finding reasonable power.” 

But AI is now intensifying both of them dramatically.

And it’s also forcing the industry to rethink how infrastructure itself gets built.

Liquid cooling came up several times throughout the conversation as an example of how quickly operational requirements are changing.

According to Tony, many businesses are still trying to catch up with the pace of that transition.

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

That’s probably true across much of the industry right now.

Technology is moving so quickly that even experienced infrastructure operators are constantly adapting in real time.

The Industry Rewards People Who Keep Learning

One thing that became really obvious throughout the episode is that Tony genuinely enjoys the fact the industry never stays still.

Even after decades in telecom and infrastructure, he still talks about learning constantly.

At one point, he said:

“Every day I learned something new because there was something that transpired new every day.” 

That mindset probably explains why some people stay in infrastructure industries for decades while others burn out or move on quickly.

Because telecom and digital infrastructure rarely reward people who become too comfortable.

• The technology changes too quickly.
• The market changes too quickly.
• Customer expectations change too quickly.

And the people who seem to thrive long-term are often the ones who stay curious enough to evolve alongside it.

Tony also made another point that probably applies to almost every career in infrastructure:

“Nothing’s going to be static. We’re changing so fast.” 

That may actually be one of the defining characteristics of digital infrastructure now.

Change is no longer occasional.

It’s continuous.

The Industry Has Always Had Bumps - And Probably Always Will

One of the more honest parts of the conversation came when Tony discussed resilience.

Because despite all the excitement around growth and technology, he was also very open about the fact that infrastructure industries are difficult.

• Markets change.
• Companies fail.
• Technologies evolve.
• Priorities shift.

And careers rarely follow perfectly smooth paths.

As he put it:

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

That honesty actually made a lot of the conversation feel more grounded.

Especially now, when digital infrastructure often gets discussed almost entirely through the lens of explosive growth and opportunity.

Because while the opportunity is clearly enormous, the industry still moves through cycles.
There are still setbacks.
There are still difficult transitions.

And long-term success probably comes from learning how to navigate those periods rather than expecting them to disappear.

Conclusion

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

Telecom and digital infrastructure have never really stood still.

The industry has continuously reinvented itself over the last two decades, from voice and connectivity to fiber, cloud, hyperscalers, AI infrastructure, and now entirely new conversations around power, cooling, and scale.

And the pace of that evolution only seems to be accelerating.

But throughout all of those changes, the people who build long careers in the industry tend to share one thing in common.

They stay adaptable.

• They keep learning.
• They stay curious
• They evolve alongside the technology instead of resisting it.

That was probably the biggest takeaway from the episode overall.

Because while the infrastructure itself may constantly change, the mindset needed to succeed inside it may not have changed nearly as much.
