Bruv. You're catching downvotes for two reasons. A: ageism and B: also not realising that tools like the "old ones" used lasted decades. Release dates are a poor metric here.
I get it, nobody actually got the joke. Should've put the () first lol.
What I'm playing off of is that the poster probably meant when VMware and such took off in the enterprise. As one would see in my post history I know about what came before and that these things are not new in fact. And in many many cases still in use today which is your second point. What started 49 years ago is still in use on the IBM z series and all of that stuff has awesome backwards compatibility. My dad started his career with 360 assembler (as can also be seen in my post history).
So I guess it's ageism in the direction of _young_ people. I hope it's them down voting. Otherwise it's misjudging peoples sense of humour ;)
