The same kind that we have now. Computer software does not work. Macintoshes and Windows 3.1 machines crash every few hours. Windows 95 machines crash every day. Windows NT machines crash every week.
Hardware engineers are brilliant.
The great strides they've made have almost obscured the stagnation in the software world. Microsoft has a monopoly and Bill Gates has a lot of money. But that doesn't change the fact that Microsoft programs don't work well enough for anything that matters. Society pays hundreds of thousands of people to keep our computing systems together with chewing gum and baling wire. Year 2000 bugs will be subsumed into the sea of bugs that these folks fight every day anyway.
