Isn't it more about that the jobs that gain due to the technology are mostly in the top 1% range? I mean, the share of income going to the top 1% increases that's sure, but most of that are huge and ever growing salaries and bonuses of managers and high-end professionals - not stock dividends. If you see stock performance (at least public stocks), both in terms of cap growth and dividend yield, you see a pretty grim picture in the last 10 years compared to older times. Privately held companies are somewhat in the shadow here, but there is no big reason to think they are doing much better than public ones. Stock appreciation and dividends are what forms income of capitalists.

So it is change of the salary distribution to the top 1% (to the extent that it dilutes that said 1% of many smaller capitalists that used to be there with some ex-proletarians) from lower income groups, not shift of focus from capital to labor.

Personally all rich people i knew 10 years ago were business owners or co-owners, with addition of a few corruptioners. Now it is about even between business owners, corruptioners, and high-end professionals who don't even steal where they work. Maybe that is my personal experience/change of my contact circle, maybe a trend.
