Weeeellll... yes and no. You aren't wrong, but I would just note that mainframes were remarkably reliable. They pushed a lot of boundaries on things that we still kinda struggle with today in terms of data integrity, redundancy, hot-swapability, recovery, etc. No question that today's systems are faster and perhaps in some ways more affordable. Definitely the case that the average person wanting to learn about software has more resources and tools available that once upon a time required access to these multi-million dollar machines. But, there's definitely tradeoffs between those centralized systems and our distributed systems of today.
