The Future of the Web is Peddling Endless Amounts of Cloud Frameworks

The number of web sites that need global edge computing is vanishingly small. More realistically you need a 20+ year old technology called a CDN to run your mostly static site.

Edge computing doesn't even solve any of your real problems here. I18n, l10n, international taxation/currency/payments, data-at-rest/GDPR/privacy laws. And then it introduces new problems, such as data partitioning. Are you going to partition at the edge and deal with tricky sync issues (CAP, anyone??) or are you just going to call back to your centralized DB server a thousand miles away from that edge? You know what's even faster than running that code on an edge device? Running that code on the user's phone or laptop. And you can get there. With a CDN.
