Big Tech’s big AI buildout will not end until someone stops it

Big Tech companies Amazon, Microsoft, Alphabet, and Meta are continuing to invest heavily in AI data center buildout, with plans to spend at least $720 billion this year and at least $1 trillion in the coming years. Despite this significant spending, the companies have yet to see a return on investment from AI, and investors are starting to get anxious about when they will see a payoff. The continued spending has sparked concerns about the environmental impact of data centers and the potential for government regulation, which could impact the companies' plans.
