10 years ago, I would have felt exactly the same; but you have to look which way the wind is blowing and think what life will be like for younger generations and not necessarily for ours.
I wouldn't have dreamed of restricting myself to an auto-only licence (and I was physically, cognitively and neurotypically privileged enough that it was a free choice for me) when I learned... but that was 30 years ago.
Just as I have no intention of bothering to teach my DS how to change a typewriter ribbon or how to get a camera film processed once you've taken 24/36 photos, I realise that the near future of motoring is going to be almost exclusively auto.
There was a news article the other week saying that 26% of new driving tests now are for auto licences, whereas it was something like 6% only a decade ago.
I'm not a fan of electric cars and would prefer to drive an ICE car for as long as practically possible; but on the auto vs manual front, I think manual vehicles - even vans - are going to be in a minority before very long.
Actually, I think that, before long, the idea of an individual person actually driving the car will seem quaint and old-fashioned. Never mind the question about manual vs auto driving licences; driving licences themselves will probably be virtually obsolete save in a few specific professions. The automatic cars of the not-too-far-off future won't just not need a gear stick; they also won't need a meatbag to control them!!
One thing I'd humbly suggest about EVs before then, though, is not to be too optimistic about the cost advantages remaining as they are indefinitely. They've already started to remove the zero-VED charges from EVs, now that they're getting so widespread and are no longer seen as a pioneering choice, and I could well see electricity charges being hiked massively once there's no alternative and the grid supply and infrastructure has to increase massively to accommodate millions more of them being charged every night.
