2) The SF Bay Area has never had a ventilator shortage. In fact, we gave away 500 in March/April to other states because we have too many.
3) The article mixes up various timelines into an incoherent wall of text - General AI, corona pandemic and global warming effects all have different timelines.
4) The USA is run by oligarchs who have a policy of discarding workers, so that completely undermines the article - the unemployed will not be working on moving cities inland, they will just be forgotten and destitute.
