If you offload the computer to the cloud, and don't need to do anything graphically intense, it makes daily driving an underpowered tablet very easy.
What do you mean "still"? Those are brand new RISC-V CPUs, or were a year ago when they came out.
The base RISC-V specification which the current cores implement (except the ones from the last couple of months) was not even formally frozen and published yet when the Pi 4 came out. Getting comparable RISC-V boards out in 4 years was a great effort. Note that the Pi 4 arrived eight years after the ARMv8-A spec was published.
That original spec doesn't contain a lot of important things such as SIMD which make a huge difference to those Geekbench scores. They are not comparing like to like.
By this time next year we'll have RISC-V boards performing better than the Pi 5, less than two years after it (possibly 1.5 years).
A year after that, RISC-V things currently well into their design pipeline will be somewhere between Zen 1 and Apple M1 performance.
The rate of progress is incredible. In the last 2-3 years many designers of current CPUs from Apple, Intel, AMD, Arm, Qualcomm have moved to RISC-V companies.
Short answer: Absolutely not, and you pretty much summarized it in your comment. RISC-V cpus are still at the performance level of Raspberry Pi 4, a $50 computer from five years ago.
