Yes, in ways that were actually greatly beneficial. Some companies were complete vaporware, but it proved a huge boom for fibre optic infrastructure and on the whole, building out modern telecom infrastructure. In a few short years, people went from dialup and T1 connections to DSL and high-speed cable. People weren't connected, and now they suddenly needed to be. It was an entirely new enterprise.
Unfortunately, these AI datacenters aren't really the same. They're not benefitting the public in a lasting sense. These are hot, they're loud, and they're expensive. The biggest benefits you may see from them after the bubble bursts is the infrastructure that was required to sustain them.
Improvements to sustainable, and cleaner energy sources are probably the biggest benefits. Reclaiming and rebuilding old nuclear plants, increased solar and wind projects. Governments that are willing to sell their constituents down a river for the business of a tech conglomerate won't benefit from this, but for the states that are now passing legislation to require these kinds companies to put their money into the communities they want to operate in may build lasting improvements.
It's a small silver lining, but it's there. That said, I can only imagine that when these companies see their business begin to get buried under the landslide of debt and reality that they will do everything in their power to escape liability for the waste of resources.
That seems like a rather arrogant tone to take. Reverse proxies are complicated. Easy to set up, but challenging to configure depending on what your needs are. Not everyone wants a homelab.
Everyone's journey starts somewhere and sometimes people's needs just don't extend beyond the easier choices available.
