It's not really a mainframe because the RAS story (Reliability, Availability, Servicing) story is sorely lacking compared to what a true mainframe gives you. So a midrange machine like AS/400 is probably a better comparison.
An AS/400 has a similar RAS story to mainframes than to Oxide/Dell. Oxide is closer to Dell (Oxide RAS is effectively the same as any sled hyperconverged) than they want to admit.
When the AS/400 came out circa 1989 or whatever, you could replace an entire mainframe with a box not much bigger than a mini fridge. The hardware is built for high reliability, and the OS and application software stack have a lot of integration. If Unix is "everything is a file" then AS/400 is "everything is a persistent object in a flat 64 bit address space."
The result is a system that can handle years of operation with no downtime. The platform got very popular with huge retailers for this reason.
Then in later years the platform got the ability to run Linux or Windows VMs, so that they could benefit from the reliability features.
Hi Brendan. Thanks for the update. Ignore the haters.
WRT "AI saving the planet", obviously.
We need ungodly amounts of machine learning. Weather modeling, forecasting, resilience planning, risk mgmt, planning, etc.
To implement virtual power plants (aka P2P distributed grid), everything needs to get smart. Just this transformation alone is a generational project.
There's dozens more of "must have" stacks we need to tackle climate crisis. Replace industrial heat. Decarbonize agriculture. Build out geothermal. Find and stop methane leaks. Pretty much everything needs a makeover, really.
OpenAI is as good a place (for you) to start as any.
My personal counterpoint is Norman's thesis in Things That Make Us Smart.
I've long tried, and mostly failed, to consider the tradeoffs, to be ever mindful that technologies are never neutral (winners & losers), per Postman's Technopoly.
DOET (neé Psychology of Everyday Things) deeply influenced me. Articulated things I had observed, experienced. Expanded my thinking.
I was using, teaching, and developing for AutoCAD at the time. Knew nothing about UI beyond my intuition. Just perplexed by how difficult it was for most to use.
Reflecting back, Norman's treatment of mental models and kinds of errors were the most impactful, evergreen design challenges I faced.
IIRC, Bryan Cantrill has compared the value proposition of an Oxide (rack?) to an IBM AS/400.
