We are only a few years into the '20s, but by any measure, it's been an eventful decade so far. It’s frequently been said that we’ve already seen five years’ worth of technology-driven change packed into the last 18 months, mostly out of necessity, since the start of the Covid-19 pandemic. And artificial intelligence (AI) development certainly hasn’t lagged behind. Back in 2019, in what seems like another lifetime, I had a stab at picking out what I thought were the most significant developments so far in the history of AI. With everything that has developed since then, I thought it would be a good idea to round up the biggest breakthroughs and most significant developments of the current decade. Unsurprisingly, many of the biggest and most headline-grabbing developments have been in the area of healthcare. However, ongoing research has also pushed boundaries of what is possible with natural language processing and vehicle autonomy.
