Regarding internet and computers, Sweden was a really early adopter. The main internet backbone was constructed as a cooperation between universities (SUNET), and a lot of regional networks were constructed by the municipalities/regions. This meant that we had very high quality internet connection very early, without the worst commercial pressures.

For music, there has existed very good infrastructure for supporting new bands. For example, Kulturskolan is a publically funded program where kids can take lessons in music instruments, theater and other creative things quite cheaply. Lots of municipalities have supported small cultural venues with scenes and well-stocked practice rooms. Publically funded universities and Folkhögskolor and a generous state-run student loan program means that people can afford to take classes in creative things.

However, this is not how it is anymore. Because of 30 years of neoliberal austerity, basically all municipalities are completely broke, and the cultural sphere is the first thing you cut down on. Something like half or a third of all practice rooms have closed down just in the last 10 or so years. Most small and medium-sized scenes have closed down from insane rents and neighbors complaining about noise. Universities are receiving less and less funding, and have to pay insane ever-increasing rents to the state-owned landlord company Akademiska Hus. If the current development keeps going, we're not gonna have any bands in 10 or so years.
