I would go even further and argue that vast majority of businesses will never need to think about distributed systems. Modern hardware makes them irrelevant to all but the most niche of applications.
10 to 15 years ago, you could argue, however implausibly, that hardware constraints meant vertical scaling was impossible, and you were forced to adopt a distributed architecture. Subsequent improvement in hardware performance, means that in 2025, vertical scaling is perfect acceptable in nearly all areas, relegating distributed architecture to the most niche and marginal applications. The type of applications that the vast majority of businesses will never encounter.
