Technology, science, physics - it's all philosophy

HH

Rabbi Nachman considered even accomplished physicists and engineers to be philosophers (Sichos - Words of Rabbi Nachman 5), may HY save us from such humiliation. He wasn't impressed by the science they figured out and their inventions. He said that every new idea has a time for its revelation, and when that time comes it alights and dons in someone's mind, and this is by impure ways (ibid).

Rabbainu revealed that in messianic times people will be flying around on their own personal flying machines. We have yet to achieve that, but it upcoming.
