This is a good point concerning current gait recognition technology. However, I don’t doubt it will improve. On longer timescales, this should happen naturally as compute gets cheaper and more data gets collected. On shorter timescales, this can be accelerated using techniques such as synthetic data generation.
Perhaps there is a natural limit to gait recognition, if it turns out that people can’t be uniquely identified from their gait, even in the limit of perfect data. But if there isn’t, then in 10 years, “94%” will turn into “99.999%”, or whatever is needed for gait recognition to be worth thinking about.
In this situation (and in the situation where I leave my phone at home), this question becomes relevant again.
