How much can it last? I think that someone who wanted to have already left this industry, but there is no point in leaving now.
How long it will last no one knows))). Maybe a year or two. Do not even be surprised at this.
No one here can deliver specific deadlines, projects are developing for a very long time.
It seems to me that the timing is not an indicator at all. It is better not to invest in time but provide the user with a finished product.
