Hear me out.
Sell your Spark clusters NOW.
Do not listen to the hype.
The things coming in the next 6 months will make that machine look like an overpriced toy.
Intel, AMD, Apple, and even smaller Chinese firms are about to dominate on price and performance. There will be no reason to even think of owning a spark at current prices. They are not good general machines either where the competition like AMD Ryzen AI Halo or Mac Studio are whole PCs that make incredible work machines in addition to providing comparable or superior inference.
