I would say a prerequisite for safe retirement is to have enough to buy a home outright in cash, otherwise mortgages will weigh you down like a stone:6% interest on a 1 million gbp loan in the UK is unpayable for majority of people even in London and yet you wont find anything worth buying there below that price.

The tech industry in general suffers from a cancerous disposition towards encouraging fake traffic, fake users, and fake online activity because it makes businesses appear to be more successful than they really are. Criminals are fed millions of dollars by executives who think that price is worth paying if it will mislead investors into believing inflated valuations.

I'm sorry but that's literally advocating for spaghetti code. If the author really wrote a lot of real world code, it doesn't look like it was clean or well structured.
