My colleagues and I conducted a small study and found that compared to a human therapist, people find chatbot therapy less useful, less enjoyable, and their conversations less smooth: http://library.usc.edu.ph/ACM/CHI2019/2exabs/LBW1712.pdf
It is true that this case has the signs of unnecessary, racially-biased police brutality written all over it. It is also true that gentrification in SF is causing serious problems and culture clashes.
But I think it's unfair and quite a stretch to take this example and say that 'gentrification' is directly responsible for this killing. The underlying problems here are racism and police brutality, which in this case are correlated to, but an entirely separate issue from, the sudden influx of wealth.
