The AI Revolution: Understanding the Technology Behind the Investment Boom

If you’ve been following the stock market over the past couple of years, you’ve probably noticed that artificial intelligence (AI) has become one of the hottest topics in investing.

Nearly every earnings call now mentions AI. Technology companies such as Microsoft (NASDAQ: MSFT) and Alphabet (the parent of Google) (NASDAQ: GOOGL) are spending hundreds of billions of dollars building AI infrastructure, while businesses across almost every industry are looking for ways to incorporate AI into their products and services. Yet despite all the attention, many people still aren’t sure what AI actually is or why it has become so important.

That investment involves far more than the AI software most of us interact with. It spans chips, memory, networking equipment, data centres, electricity, cloud computing, and the software and applications that turn AI into something businesses and consumers can use.

Before we can understand why companies are investing so heavily in AI, it helps to first understand what AI is – and what it isn’t.

In Part 6 of The AI Revolution, we explore why the fear of falling behind may be just as powerful a force behind today’s AI spending as the potential rewards.

AI Disrupters

For the past few years, anything connected to artificial intelligence (AI) felt unstoppable. Investors poured money into AI-related companies, pushing valuations higher as excitement around the technology grew. There were concerns about the massive capital expenditures required to build AI infrastructure, but the dominant narrative was simple: invest now, dominate later.

This year, that tailwind has started to feel more like a headwind. Investors shifted from asking, “Who benefits from AI?” to “When will companies start seeing a return on all that investment?” – and now, “Who gets disrupted by it?” That change in mindset helped trigger the recent meltdowns.

Three Reports, One Story: Connecting the Economic Dots

This week gave us something we don’t often see – all three major US economic reports landed at once. Because of the recent partial government shutdown, the labour report, retail sales data, and CPI inflation numbers were released in the same week. Normally, these reports are spaced out, with jobs data arriving first and inflation and retail sales following mid-month. Seeing them together offers a rare opportunity to step back and view the American economy through three connected lenses at the same time.

AI Turns From Tailwind to Disruptive Headwind
This past week, markets came under pressure as investor sentiment around software companies shifted sharply. While higher interest rates and stretched valuations had already been weighing on the sector, what really rattled investors was a growing belief that parts of the software and professional services industry may be facing real disruption, not just a temporary slowdown.

Monthly Portfolio Update January 2026

January was a bit of a rollercoaster for markets. Indexes pushed to new highs, pulled back to catch their breath, and climbed again, before fading late in the month but still finishing in positive territory. Volatility (also known as buying opportunities 😊) was the name of the game.
