Looking round the political news and similar sources (recently), then filtering it, to stay within the electronics and similar industries, it seems.
That there are real worries, that currently, decent, hardworking, well paid, electronics engineers (as well as related people, such as software experts/developers). Could end up deciding to leave the US. Hence a significant brain drain from America.
Similarly, the flow of suitably qualified/experienced/talented, electronics engineers (and similar), into the US, could somewhat dry up.
Even potential upcoming electronics hobbyists (who may have then studied/worked, in the future) in electronics/computing, may be put off. If the ready supply of very cheap electronic parts/PCBs(custom) and stuff, very affordable even for upcoming hobbyists, who have not left home yet, or are still studying.
Could be partly hard-hit, if the prices of such things, goes up considerably, because of tariffs.
I.e. Instead of growing the electronics and other high tech industries, it could have the opposite effect.
