I will never understand why people are so obsessed with the extreme of the thin client ideal. They are a good choice in a world where the network is fast and low latency, while client devices are underpowered and expensive (VT100s in a lab with minicomputer in the next room). Meanwhile, we've lived for at least the past two decades in a world where the network (on the cellular and home broadband ends) is slow and high latency but our client devices are incredibly powerful and cheap. The period of time where this makes any sense for anyone except for proprietary software vendors that want to close off any possibility of pirating their products has long since passed.
The appeal of "compute clusters" for most "power user" tasks especially diminishes when you realize that shitty off-the-shelf PCs from 10+ years ago were perfectly capable of running programs that did most of same stuff as their modern versions. New functionality has been added, of course, but most of the increase in resource requirements came from selfish programming from generations of programmers that never learned how to optimize. There's no reason that a Chromebook with a cheapo ARM or low-end Intel SoC shouldn't be able to natively run a better optimized graphics program like Paint Tool Sai with CPU time/battery to spare.
