I think you quoted the wrong person.
That said, I think it depends where you live. Around here most vapers are 30 or older. They want to vape like they smoked. Most think big plumes of vapor is obnoxious and want MTL tanks and ego type battery's. There are a few younger (late 20s) that hang out at the juice bar at the one shop that has one. They are the only people I see with box mods and drippers.
Different places different demographics.
Different kinda smokers I guess. Age wise I'd say the average would be about 50 like me but that may just be the people I know are 50. My son would be the youngest I interact with at 30 Top end might be closer to mid-50's. My mother does not smoke but she belives in vaping and tries with the old smokes at the home but they'd rather just smoke and honestly they made it that far let them go.
I agree on the being like smoking and to me tootle puffing is nothing like smoking. I did it for a long while and I suffered mightily. It wasn't until I started sub ohming I put smoking way behind me. And thats how I start friends out these days. The friends I helped started on tootle gear are all back smoking, and I don't really blame them. They won't try thr new gear cause they say it won't work. The ones I set up with sub ohm are all doing great, for now at least.
I STRONGLY ugre all smokers to start with sub ohm. Sub ohm is the easier softer way. Like AA for smokers. Tottle gear is like iron willpower dry drunk way. If it works for one then fine but I recommend the easier way.

) And my subtanks are used with the RBA and my usual 1.5 Ω coil.
