This is going to be an unpopular reply I imagine but this person is not well and their behavior should not be imitated. This is a classic example of omnicause anxiety, like people who refuse to have children because of all these things happening in the world as if the world hasn't always been a mess. Frankly, ridiculous.
Its a problem of the privileged in both cases — a first world problem. People with real problems do not think like that.
It's part of this nihilistic undercurrent, especially among Millennials and younger generations. "I'm not having kids, have you seen the world?" "I'm not saving for retirement, Social Security won't exist and the oceans will swallow the continent by the time I reach retirement age." "I refuse to use AI tools that could help me create new things and reach my goals, because the influencers told me AI is going to poison the water". Quite sad actually.
