Artificial general intelligence (AGI) -- AI systems capable of performing intellectual tasks at or above human level across all domains -- could arrive sooner than many expect, with some experts projecting development as early as 2026.

Unlike today's specialized artificial intelligence (AI) tools that excel at specific tasks like generating text or images, AGI would match or exceed human capabilities across any intellectual challenge. This technological breakthrough could revolutionize human society and unlock an estimated $100 trillion in economic value, according to Nvidia CEO Jensen Huang.

The window to position investment portfolios for this seismic shift is narrowing. While current generative AI tools have driven impressive productivity gains of 14% to 56% in specific tasks, AGI represents a fundamental leap forward that could reshape every sector of the global economy.

One Vanguard exchange-traded fund (ETF) stands out as a compelling way to gain broad exposure to this transformative trend. Read on to find out more.

A proven technology powerhouse

The Vanguard Information Technology ETF (VGT -1.56%) provides investors with access to 314 technology companies at the forefront of AI development. The fund's top holdings read like a who's who of AI leaders, with Microsoft, Apple, and Nvidia comprising over 44% of the portfolio at present.

This concentrated exposure to AI pioneers has helped drive impressive returns. The Vanguard Information Technology ETF has delivered a 27% total return year to date, outpacing the S&P 500's 25.5% gain. More importantly, the fund has averaged a whopping 13.45% annual return since its inception in 2004, trouncing the S&P 500's performance over this 20-year period:

Cost advantage meets innovation exposure

The Vanguard Information Technology ETF shines in its cost efficiency. The fund charges just 0.10% annually, dramatically below similar funds' 0.95% average expense ratio.

To put this in perspective, a $10,000 investment would incur just $10 in annual fees with this Vanguard ETF, compared to $95 with the average technology fund. Over decades of compounding, this 0.85% cost difference could translate into thousands in additional returns as more money stays invested in the technology companies driving AI innovation.

What's more, the fund's portfolio spans the entire AI ecosystem. Beyond software giants, it holds significant positions in semiconductor manufacturers (29.7% of assets) and hardware companies (17.6% of assets). This broad diversification within the technology sector provides exposure to both AI/AGI development and the critical infrastructure enabling this game-changing innovation.

A low-cost vehicle to buy ahead of the AGI revolution

While AGI's exact arrival date remains uncertain, the technological groundwork is being laid today. OpenAI CEO Sam Altman predicts humanity is entering an "intelligence age" that will bring unprecedented prosperity. The timeline could be shorter than many expect.

Leading AI executives, including Altman, project human-level artificial intelligence should arrive by no later than 2027, with some even suggesting it could come as early as 2025. The Vanguard Information Technology ETF, with its concentrated holdings in AI pioneers, offers investors efficient exposure to this potential transformation.

Still, the risks are significant and warrant careful consideration. Technology stocks can be exceedingly volatile, and AGI development faces substantial hurdles. Energy requirements, computational limits, and regulatory challenges could all delay progress. A measured position size in this ETF allows investors to participate in potential upside while acknowledging these uncertainties.

The Vanguard Information Technology ETF's balanced exposure across the AI ecosystem -- from software giants developing AI models to semiconductor firms building the computing backbone -- provides a thoughtful approach to this technological revolution. For investors who believe in AGI's transformative potential, this fund offers a well-diversified entry point to computing's next great leap forward.
