first off... it was a bloody joke for the most part but yes many EDM mix sessions have tons of tracks albeit small but some have well over 100. also take into account orchestration mixes... some are not small parts but many sessions still have tons of tracks. who in their right mind would use a 'per instance' scenario on large projects these days?
you could easily do 100+ and use only one instance without summing a thing. have you ever thought about rendering/bouncing/printing? you could use a bus and run say 1000 tracks through it and print them ALL individually as single tracks before mixing them. would it not be the same as using 1000 tape plugs which would crash any system? i venture to say yes
as for my own personal projects... i rarely go over 30 tracks... usually far less because i like more gritty garage band sounds but i have mixed other's projects that can get quite large. it is my advice one should always ask first before attempting to read another's mind as to what was meant. imo it saves on sounding foolish. lol cheers
