I voted depends on the diver.
I see divers who start diving and know that they want to become a technical diver and they also are naturals in diving AND (also most important) want to train and improve.
On the other hand I also see divers who want to become a technical diver, but don't have te skills, don't want to practise, etc. This divers cannot be a full cave diver in 150 dives.
This discussion also remembers me about the discussion if it is possible to become full cave in 1.5 year from starting diving. Also this depends on the diver.
Looking back at my own path, I directly knew during my open water that a twinset was my way. I liked going in dark and deeper waters. So I asked my ow instructor to take me on the last dive to the maximum depth of my cert. The water is then 4 degrees, completely dark and it was my first time diving with gloves and a hood. Nothing to see, just going down folling a line, but I liked it.
Then was my question: I want to do technical diving, what is the way to do this? Just a normal question of a diver I also have to answer as instructor. The answer was: go diving, get experience. My next question was: how much experience? No answer, just go get experience.
I bought a normal recreational bcd, just because people said: you don't have enough experience to start technical diving. Never was the question answered about how much experience I needed.
I became member of a club to get my 2* because I decided to do icediving in winter. Also in the club they said I was not experienced enough for 2*. But I had already 26 dives and had done tidal dives and deep dives and nightdives without instructor as there was nobody. And the required amount of dives for cmas was 20. So I was experienced enough. They just said it because they could not offer me an instructor to do the dives officially as a course dive. But also complaigned about my own autodidactial dives.
I did my padi aow then. My first dive was 1 august, we talk now about half november and I had 55 dives. Still no answer about technical diving. I bought a drysuit and learned myself drysuit diving as there was again no instructor available on the day I bought that suit. I had to wait 2 weeks, that is too long if you buy such a thing. So I learned it myself. Not hard.
Then on dive 75 I did my first icedive.
And I decided to sign up for 3*/dm. That was also a long way to finish as again no instructors in the club, so I paid an instructor to teach me it. And then I had 200 dives, decided to by a twinset. For tdi 100 dives are needed to do the 100m course, so I found myself experienced enough to start technical diving.
On 1 april I finished my ART course. On 16 april I finished my 'zero to hero' 1 week cavern-full cave course. 18 months after my open water cert. Certifying dive was dive no. 390. In october I was full trimix diver and did my first 100m dive, dive no. 521.
So in 2 years a diver can be from open water to certified as full cave and full tx. I just want to be in the water as much as possible. I did not finish my full cave course in 150 dives. But in 18 months. From ART to full trimix took 6 months. The main reason here is because we don't have deep waters.
My diving was always motivated to become a technical diver. And I am a little bit a natural also. I am also partly an autodidact. I watched movies, tried to practise the finkicks, then took a selfievideo, watched it till it looks like on the videos on youtube. I read a lot about diving have over 300 different books about diving in a lot of languages from animals, technical diving, saturation diving, rebreathers, to instrutor manuals.
So yes I strongly believe in the depends on the diver. I am also pro cavern-intro-full cave in once courses. The reason is here: with cavern you can do nothing. With intro, most divers around me go within 5 dives over their limits, so it is better to teach all in once for most divers.
Of course I have to tell people they are not ready for things. And I do. I also advice sometimes a person not to go further than intro to cave. But normally I prefer to teach people who are confident, experienced divers when they start cavediving. I also want that people already have their adv. nitrox before moving into cave. When they do it with me, I know how they are in the water. If a new diver comes, we do a dive to see if the skills are ok to start cavediving. And the trim and bouyancy must be on the full cave level.
I teached last year a 2* diver and if that diver comes to me to become a cavediver I will say no. He is safe enough in open water on that level, but he has not the awareness, trim, bouyancy, etc to start cavediving. Of course a diver can become better in time I don't see him, and yes, I have to dive with him again to really say yes or no (I don't judge based on earlier experience with someone), but from what I saw then it is a no.
I also teached an open water course and that diver has now about 40 dives and already a twinset. If he asks me to train him as a cave diver, we could start with advanced nitrox. He is a fast learner and wants to learn the skills I have. So even if we are not in a cave yet, we can train towards cavediving. He knows that.
If a diver comes to me with the question about experience, I answer most times this: it is a difficult answer. You have guidelines from agencies with minimum amounts of dives. But there is also a personal thing, natural, willing to learn, etc. But if you really want, start practising basic skills in open water.
Sorry for the long answer as there is no short answer on this question
