I think the long term trend will be good for software people but I think something like the dotcom crash is due. There are way too many questionable startups only made possible by excessive investment money floating around. I was around in 2000 and once investment started drying up only a little the whole house of cards came down because a lot of companies "sold" unprofitable products to other unprofitable companies. I think the situation is very similar now.

I feel like this has already been happening for years... probably longer than that. I find a lot of the people I work with were pulled away from other industries. Some industries are over-represented, like science, engineering, education.

I think amount of people who are capable of and willing to do software development is limited. Most "normal" people I know would hate the job.
