Mainly because 'modern' personal computers are orders-of-magnitude more capable than the minicomputers of yesteryear. While 'playing' with emulators of the PDP8 minicomputers recently, I realised that my Z80 of 1980 was more capable than one of the PDP8s of the mid-1960s. My 'expensive' ($2,000) microcomputer from 1980 was as good as a minicomputer worth $120,000 in 1966. That 1980 microcomputer is primitive in comparison to today's 'hobby' Raspberry Pi which sells for about $100 in total.
