TSMC’s AI chip empire has a hidden weakness, and it isn’t water
TSMC’s chief executive said Taiwan’s most urgent semiconductor shortage is no longer just water, power or land, but the people needed to sustain the island’s role at the centre of the global AI boom.
Speaking at a ceremony for a new science park in Pingtung, southern Taiwan, CC Wei said the world’s largest contract chipmaker still worries about water security, but talent remains the constraint that most concerns the company.
The comments highlight a deeper challenge for Taiwan.
The island produces most of the world’s most advanced chips, giving it a strategic role in artificial intelligence, smartphones, data centres and defence technology.
Yet the same success has intensified pressure on local infrastructure and the labour market.
Water remains a strategic risk
Wei’s remarks came during heavy rain, a welcome sight for an industry that consumes large volumes of ultra-clean water.
He joked that only recently he had been asking whether TSMC would need to rely on water trucks if supply conditions worsened.
Southern Taiwan is typically drier than the north, and reservoirs often fall during winter. The problem is not theoretical.
In 2021, Taiwan imposed broad water restrictions after its worst drought on record, exposing how climate volatility can affect a sector that global technology companies depend on.
President Lai Ching-te, who attended the event, said the government was close to completing plans to connect reservoirs across the island.
The aim is to improve water retention, distribution and efficiency, reducing the risk that regional shortages disrupt industrial output.
For TSMC, that would ease one of the so-called “five shortages” long cited by Taiwan’s chip industry: water, power, labour, land and talent.
Talent gap becomes the bigger worry
Wei made clear that even if water, land and electricity pressures are reduced, Taiwan still needs more engineers, technicians and skilled manufacturing workers.
That is especially important as AI demand accelerates and chipmaking becomes more complex.
Advanced semiconductor production depends not only on expensive equipment and stable utilities, but also on a dense ecosystem of trained workers who can run fabs, develop processes and support research.
Lai said the government is also working to attract and retain foreign talent, including by easing work-permit procedures.
The challenge will be particularly sharp in more rural areas such as Pingtung, where officials want new science parks to create jobs without losing workers to larger urban technology hubs.
Taiwan remains the centre of gravity
TSMC’s warning comes even as the company expands overseas.
Its Arizona investment has grown to $165 billion, covering six semiconductor fabs, two advanced packaging facilities and an R&D centre.
That expansion reflects pressure from customers and governments to diversify chip supply chains.
But TSMC has repeatedly said its most advanced production and core research will remain anchored in Taiwan.
The message from Wei was therefore clear: Taiwan may be able to build more fabs and strengthen water supply, but the country’s chip leadership will ultimately depend on whether it can train, attract and keep enough people to run them.
