Are we losing the skills to build TINY HOMES to today lazy technology?

Are we losing the skills to build TINY HOMES to today lazy technology? Or even to walk to work?  Stand up from our computer desks to take a break?  Build communities that build the good neighborhoods?

Home building way back when:  Myself, having great-grandparents settling in Lancaster, Pa. back in the 1800's I have learned that they both built their new home by themselves. And having brought their home building skills from their distant homes far away and coming to the USA by ship and applying for their American citizenship and after they pledged their vows to the flag - they put their skills to making their own cement bricks for the foundation and hand sawed their own lumber to build their frame. 

The wall and flooring went up and soon three infants came along.  One was a son (born 1899 my Grandfather) and he learned his parents home building skills and at a marriage age of 18 years old he built his new wife a beautiful home. He used no power saw tools and hand cut all this lumber and built his own cement blocks and dug out the cellar by shovel by his own hand. He did all this while working overtime at his day job, being a volunteer fireman of his neighborhood, became captain of his soccer team, and built the first sports playing field in his neighborhood.  And never applying for driving an auto or owning a Motor Vehicle license.  

He walked to work 6 to 7 days a week and walked to the firehouse (which he help built at age ten) when the alarm went off. He died at the golden age of 89 years old and never once went to visit a doctor.  And he never did invest in any type of electrical power tool.  He passed along his home building skills to all his next of kins.   Puting hammers and nails into the hands of all his sons, daughters, grandsons, & granddaughters and teaching them the home building skills his parents brought along to America way back when.
