跪求高人翻译如下文字

译:过去50 年其实并不是发明创新的黄金时期.从1900年到1950年,改变人类生活的发明有汽车,飞机,电话,收音机,电视机--当然还有核武器和计算机.而近50年来,只有为数不多的发明.难道发明的源泉已经枯竭了吗?答案并非如此.事实上,发明的新时代才刚刚开始.

AS a matter of fact,it was not a prime time of invention or innovation over the past 50 years.There were not only automobiles,aeroplanes,telephones and radios but also nukes and computers which changed the lifestyle of mankind during the period from 1900 to 1950.Whereas,there was little invention in the recent 50 years.Is it because the source of invention has been exhausted?In fact,the answer is not,the new epoch of invention has just started.
顺便补充下：黄金时间应该是prime time 而不是翻译成字面的golden time

The last 50 years weren't the golden era for innovations. Between 1900 and 1950,
automobile, aircraft, telephone, radio, television, nuclear weapon and computers
were invented and changed the lifestyle of mankind. However, not many were invented
in the last 50 years. Is the well of innovation drained already? Not likely.
In fact, the new era for innovation has just began.

同意鱼的翻译, 有两个地方鱼可能打错字了,帮你指出来

has the well of innovations been drained
