What are Negative and positive aspects about engineering?

This is a very open question…Engineering anything in particular? Social Engineering? Food Engineering?

Sorry. Computer engineering

Computer engineering is a fickle thing.

On the plus side, it will allow you to do amazing things, and to earn good money while doing it.

On the downside, it is highly competitive, and evolves fast enough that staying current is almost a full-time job in and of itself, and if you let your skills slip them you will be trampled underfoot like it’s a soccer riot.I am a machinist that didn’t use my skills for a few years but managed to get back into the field and up to speed. Computer engineering doesn’t allow for that; even a few months out of the loop may be career-ending unless you are a quick learner.

Positive engineering aspects include difficult math, loud noises, bright flashes, and smoke.

This is also true of computer engineering.

With great power comes great responsibility. Man’s creations may be able to do things beyond what Nature’s creations can do, but the direction can be either bad or good e.g. nuclear power, electricity, internal combustion engines.

Positive: help saving the planet, choice of interesting jobs, great pay

A quick analysis was done once: engineers create wealth from knowledge and raw materials, lawyers only redistribute wealth.
