Author here; I have a lot of other posts in my personal blog about this, but: the current trends in VC-backed tech companies are about minimizing risk and following fashion, rather than any technical merit or experimentation. Said another way: if an Elixir company dies, it's "damn, shouldn't have picked Elixir!" If a Python company dies, it's "startups are hard," with no investigation behind what Python cost you.
Elixir has real technical downsides too, but honestly they never come up when someone advocates against it. And this is fine, building companies and engineering culture is a social game at the end of the day.
