I am all for letting people to learn on the job. But I, personally, would rather not risk it, knowing that the difference between them "learning as they go" and already knowing it might end up making the difference between me walking free and ending up in jail.

If it was something more trivial and with much lower stakes, like a traffic violation ticket, then sure, I wouldn't be so opposed to a lawyer that is figuring things out as they go.

Also, I think you might've missed the point of my original comment. It is one thing when a lawyer might not know something due to still learning their stuff, and another one when it is clear that they arent willing/planning to do so. If someone still uses fax as their primary mode of communication and refuses to use computers altogether in 2022, I have a feeling that it isn't due to them still trying to get the hang of it.

I have never worked anywhere where engineers got basic training. They were just expected to perform, and so they would perform poorly, because they lacked so much basic knowledge. There's such inconsistency and such little understanding that they often confuse each other and waste each other's time trying to figure out simple things.

That's the bulk of the entire industry now.
