# South Asian Heritage in the GLMZ

## The Precursor: Devon Avenue and the Professional Class

Chicago's South Asian community in 2026 was small relative to the city's overall population — perhaps 200,000 in the greater metropolitan area — but disproportionately visible in specific economic sectors. Devon Avenue on the North Side served as the community's commercial spine: a mile-long corridor of sari shops, jewelry stores, Bollywood video rentals, and restaurants serving dosas alongside chaat alongside biryani, the subcontinental diversity compressed into a single street grid. The community was predominantly Indian, with significant Pakistani, Bangladeshi, and Sri Lankan minorities, and it was overwhelmingly professional-class: physicians, engineers, software developers, and academics recruited through the H-1B visa pipeline that had been funneling South Asian talent into American technical industries since the 1990s.

This professional-class foundation would prove decisive. When the climate catastrophes came, the South Asian diaspora in Chicago was not a community of laborers seeking shelter. It was a community of engineers seeking laboratories.

## The Bangladesh Submersion (2060-2110)

Bangladesh was the canary in the climate mine, and it died screaming.

The nation occupied the Ganges-Brahmaputra delta, one of the most fertile and most vulnerable landscapes on Earth. In 2026, 170 million people lived in a country where two-thirds of the land surface sat less than five meters above sea level. The math was simple and merciless: every centimeter of sea-level rise inundated thousands of hectares. Every monsoon season pushed saltwater further into the rice paddies that fed the nation. Every cyclone — and the Bay of Bengal was generating Category 4 and 5 cyclones with increasing frequency after 2040 — drove storm surges across a landscape with nowhere to drain.

Dhaka, the capital, housed 25 million people by 2050 in an area prone to annual flooding even before sea-level rise. The city's drainage infrastructure, designed for a population of 5 million, had been overwhelmed for decades. When the 2067 monsoon season produced rainfall 40% above the twentieth-century average — a figure that would become the new normal within a decade — Dhaka experienced flooding that submerged 60% of the city for three months. The economic damage was estimated at $80 billion, more than the nation's annual GDP.

By 2090, the Bangladeshi government had formally acknowledged that the nation's southern third was permanently lost. The Sundarbans, the world's largest mangrove forest, was 80% submerged. Chittagong, the country's second city and primary port, had been abandoned after the 2083 cyclone that killed 200,000 people and destroyed the port infrastructure beyond any economically viable repair. Barisal, Khulna, and the entire southern coastal belt were gone. The population had compressed northward into an increasingly desperate corridor around Dhaka and the Sylhet highlands.

The Bangladeshi refugee crisis produced more displaced persons than any single national event in human history. An estimated 90 million people left the country between 2070 and 2120. The majority went to India, which was itself struggling with coastal displacement from Mumbai, Chennai, and Kolkata. Millions more scattered across the mass driver network to Southeast Asia, the Middle East, Europe, and North America.

Chicago's Bangladeshi community, which had numbered perhaps 15,000 in 2026, grew to over 200,000 by 2110. The early arrivals were professionals — the engineers, doctors, and academics who had the resources and credentials to navigate international migration systems. The later waves were everyone else: farmers, fishermen, garment workers, and the urban poor of Dhaka's dissolved slums, arriving through humanitarian corridors that the GLMZ's predecessor governments established under international pressure.

## The Indian Coastal Collapse (2070-2130)

India's crisis was slower and larger. The subcontinent was not going to disappear beneath the waves like Bangladesh — its interior was vast and elevated. But its coastal megacities, where a disproportionate share of the nation's economic output and population were concentrated, were catastrophically exposed.

Mumbai, built on a chain of islands that had been landfilled and reclaimed over centuries, began experiencing permanent tidal flooding in its lowest-lying wards in the 2060s. The city's financial district — Nariman Point, the Bandra-Kurla Complex — relocated piecemeal to Pune and the Deccan Plateau over three decades of managed retreat that was neither managed nor orderly. By 2095, Mumbai's population had fallen from 25 million to 8 million, and the island city's southern half was a saltwater labyrinth navigated by boat.

Chennai lost its freshwater aquifer to saltwater intrusion in 2078, a catastrophe that the city's 15 million residents had been warned about for decades and done nothing to prevent because prevention required infrastructure investment that no government would fund. Kolkata, situated on the same deltaic geology as Bangladesh, experienced similar submersion dynamics on a longer timeline. Visakhapatnam, Kochi, Mangalore — the entire Indian coastline retreated, and with it went the industrial and commercial infrastructure that had made India the world's third-largest economy.

The Indian diaspora that reached Chicago and the GLMZ was overwhelmingly technical. India's IIT system — the Indian Institutes of Technology — had been producing world-class engineers for over two centuries, and the climate displacement accelerated an already-massive brain drain. IIT graduates who might have built careers in Bangalore or Hyderabad instead landed in the GLMZ's emerging tech sector, bringing with them expertise in software engineering, AI development, materials science, and — critically — neural interface design.

## The Circuit: South Asian Heritage as Technical Infrastructure

South Asian genetic heritage constitutes approximately 12% of the GLMZ's population in 2226 — a figure that represents a dramatic increase from the community's pre-collapse baseline and reflects the outsized role of South Asian technical migration in building the megacity's knowledge economy.

The Circuit is the community's center of gravity. The district's founding mythology — that it was built by engineers for engineers, a place where technical competence mattered more than corporate pedigree — is not entirely mythological. South Asian engineers were instrumental in designing the GLMZ's neural interface infrastructure during the 2140s and 2150s, when the first generation of mass-market BCIs required both the hardware engineering expertise that IIT graduates brought and the software architecture skills that Bangladeshi and Pakistani developers had honed in the global outsourcing economy of the early twenty-first century.

The Circuit's Devon Corridor — named in deliberate homage to the original Devon Avenue — is a twelve-block stretch of tech incubators, chai houses, and component shops where three languages of technical documentation coexist: English, Hindi, and a Bengali-English hybrid that Circuit residents call Bangla-Tech. The corridor hosts the annual Diwali of Light festival, which has evolved from a Hindu religious observance into a secular Circuit-wide celebration of innovation, complete with holographic displays, BCI art installations, and competitive coding tournaments that draw participants from every ancestry group in the GLMZ.

Meridian Core's financial district houses a significant South Asian professional class — descendants of the early professional migrants who leveraged their families' educational traditions into corporate advancement. The Meridian Core South Asian Business Association, founded in 2098, maintains scholarship programs that have funded over 50,000 technical educations and serves as an informal hiring network that connects South Asian-heritage graduates to corporate positions across the Big 20.

## Identity After Two Centuries of Diaspora

The distinction between 'Indian,' 'Bangladeshi,' 'Pakistani,' and 'Sri Lankan' has largely dissolved in the GLMZ by 2226, replaced by a broader South Asian identity that would have been unrecognizable — and politically unacceptable — to the nationalist movements that defined the subcontinent in the twentieth and twenty-first centuries. A Circuit engineer in 2226 who claims South Asian heritage might carry genetic markers from Tamil Nadu, Bangladesh, Punjab, and Sri Lanka simultaneously, blended with Chinese, Nigerian, and Polish heritage from generations of GLMZ intermarriage.

What persists is not nationality but practice. The food — dal, biryani, dosa, samosa — has become so thoroughly integrated into GLMZ cuisine that most residents do not think of it as 'South Asian' any more than they think of bread as 'European.' The languages survive in technical jargon and family conversation. The religious traditions — Hindu, Muslim, Sikh, Buddhist, Jain — continue in attenuated forms, often blended with other traditions in the syncretic spiritual landscape of a megacity where no single faith commands majority adherence.

The most durable legacy is institutional. The engineering culture that South Asian migrants brought to the GLMZ — the emphasis on technical education, the multigenerational investment in professional credentials, the network effects of community-based hiring and mentorship — has shaped the Circuit's culture so thoroughly that it is now simply the way the district operates, regardless of the ancestry of the people doing the operating. The Circuit runs on South Asian institutional DNA even when the people running it carry none of the genetic variant.
