More like vaporwave, 90's were industrial and office design: something to make you feel productive. No 00's kid would understand this, we did. BeOS was a mix between the potential MS Office killer and the multimedia machine capabilities from the late 90's. No cyberpunk, no friends, no avant-garde. Just a boring office cubicle + multimedia production for artists. No, not for vaporwave music. Any music. Techno, classical, R&B, metal... anything. That, and video/image editing.
The late 90's screamed "workplace", "multimedia" and the information exchange era. Brutalist and futurism.
OFC Helvetica was mimicked from press, the media and press were HUGE back in the day, they had the same power as MS, Amazon, FB, Google and Netflix today. So we tried to clone magazines, VCRs, TV's, cubicles and stereos/radios in our computers. We succeeded.
Trying to explain the 90's with "vaporwave" is ridiculous. Those could be maybe for the early 90's demoscene for PC/Amiga. They were as obsolete in late 90's as Windows 98 today.
The late 90's were about replicating the mainstream media in your computer.
