which engineering do you think is the most promising in the future?

Answer 1

I'm a mechanical, so maybe I'm biased, but I've always thought of mech Es as being generalists. So a mech E can get into a lot of different industries. In that sense, there will always be opportunites for them regardless of what may happen in a particular industry. Petroleum engineers will suffer a declining market as we try to move away from that fuel source, aerospace companies have highs and lows, etc. but mech Es have some immunity from this.

Answer 2

probably the best, but the one that will require the most continuing education is going to be computer engineering. structural/civil is always a field you can find work, but it's not always great pay. avoid petroleum at all costs.
any medical (bio/genetic) is, usually, considered a passion career; lots of satisfaction, but not much money BTW, this question has been asked by engineering students/potential students forever-good luck petroleum paid $500 to 1,000 per day; then the bottom dropped out and you could find masters degrees working as cashiers at coffee shops

Answer 3

Bio or Genetic engineering - it can most diseases we know - Cancer, HIV, all Viruses and genetic disorders

or become a Doctor

Answer 4

environmental engineering - we need clean water to drink, better land management practices, preservation and conservation of our natural resources, and innovative ways to dispose of wastewater.
